thaibebop Posted April 5, 2006 Share Posted April 5, 2006 Are you a thread killer? Many times I find a thread and I respond to it, only to find that I am the last person to respond to it, and it was very active before I got there. Bad timing perhaps? Okay, so I wonder what about my post, is that is what it was, killed the thread. Got me thinking, how do you kill a thread? So, for those who kill threads on purpose and those like me who do it by mistake, what are the best ways to kill a thread? Link to comment Share on other sites More sharing options...

taxexile Posted April 5, 2006 Share Posted April 5, 2006 At the far right are several large areas of activity in numerical linear algebra and related topics, typically, the study of individual matrices or transformations between (large-dimensional) real vector spaces. Numerical linear algebra per se (e.g. the determination of fast methods of solving thousands of simultaneous linear equations, the stability of eigenvalue calculations, applications to finite-element methods, sparse matrix techniques) are parts of 65: Numerical Analysis, particularly 65F: Numerical linear algebra. Here we include several fields of inquiry into the underlying linear systems and their applications. In this category we might include 15A06: Linear equations, 15A09: Matrix inversion and generalized inverses, 15A18: Eigenvalues and singular values, 15A23: Factorization of matrices (SVD, LU, QR, etc.), 15A12: Conditioning of matrices, as well as applications to physics (15A90), Control Theory (93) and Statistics (62) such as what is there known as Principal Component Analysis. Related topics include those of importance in 90: Operations Research (especially linear programming) such as 15A48: Positive matrices, 15A39: Linear inequalities, and 15A45: Miscellaneous matrix inequalities. The circles in shades of red in the lower part of the graph show connections with other fields of algebra. Furthest down is 15A72: Invariant theory and tensor algebra, which crosses to the study of invariants in Group Theory (20) and in polynomial rings (13: Commutative Algebra and 14: Algebraic Geometry). Certain sets of matrices form well-known groups, particularly the Lie groups (22) and algebraic groups. Closer to the center of the picture are connections with Number Theory (10 and 11), especially 15A63: Quadratic forms. There are several connections with ring theory (16: Noncommutative Rings, 17: Nonassociative Rings, 19: Algebraic K-Theory); indeed many of the key examples of such rings involve collections of matrices, including the full matrix rings and Lie rings, and rings of matrices are used for representing groups and general rings. Related disciplines within Linear Algebra include 15A27: Commutativity, 15A30: Algebraic systems of matrices, 15A33: Matrices over special rings (including 12: Fields), 15A36: Matrices of integers, 15A75: Grassmann algebras, and 15A78: Other algebras. Tensor products in linear algebra (15A69) mirror such constructs in other algebraic categories. Nearby are several fields in discrete mathematics, including the use of matrices for the representation of combinatorical objects such as graphs (05: Combinatorics), extremal matrices, permanents (15A15), and applications to 68:Computer Science, 94: Information Theory (e.g. linear codes), and 39: Difference equations. In the upper left are the papers in "geometric algebra", including 15A66 (Clifford algebras), 81 (Quantum theory), 53 (Differential Geometry), and 58 (Analysis on manifolds). In the upper right are the topics appropriate for 60: Probability and 62: Statistics, including 15A51: Stochastic matrices and 15A52: Random matrices, and applications to statistical mechanics (82) and the sciences (92). Linear maps of geometric interest are considered in the geometry pages (51, 52). For example, rotation matrices and affine changes of coordinates come under 51F15. Sets of matrices qua sets arise geometrically as well; for example certain families of matrices form manifolds, and even topological groups (22). Subfields There is only one division (15A) but it is subdivided: 15A03: Vector spaces, linear dependence, rank 15A04: Linear transformations, semilinear transformations 15A06: Linear equations 15A09: Matrix inversion, generalized inverses 15A12: Conditioning of matrices, See also 65F35 15A15: Determinants, permanents, other special matrix functions, See also 19B10, 19B14 15A18: Eigenvalues, singular values, and eigenvectors 15A21: Canonical forms, reductions, classification 15A22: Matrix pencils, See also 47A56 15A23: Factorization of matrices 15A24: Matrix equations and identities 15A27: Commutativity 15A29: Inverse problems [new in 2000] 15A30: Algebraic systems of matrices, See also 16S50, 20Gxx, 20Hxx 15A33: Matrices over special rings (quaternions, finite fields, etc.) 15A36: Matrices of integers, See also 11C20 15A39: Linear inequalities 15A42: Inequalities involving eigenvalues and eigenvectors 15A45: Miscellaneous inequalities involving matrices 15A48: Positive matrices and their generalizations; cones of matrices 15A51: Stochastic matrices 15A52: Random matrices 15A54: Matrices over function rings in one or more variables 15A57: Other types of matrices (Hermitian, skew-Hermitian, etc.) 15A60: Norms of matrices, numerical range, applications of functional analysis to matrix theory, See also 65F35, 65J05 15A63: Quadratic and bilinear forms, inner products See mainly 11Exx 15A66: Clifford algebras, spinors 15A69: Multilinear algebra, tensor products 15A72: Vector and tensor algebra, theory of invariants, See Also 13A50, 14D25 15A75: Exterior algebra, Grassmann algebras 15A78: Other algebras built from modules 15A90: Applications of matrix theory to physics 15A99: Miscellaneous topics Link to comment Share on other sites More sharing options...

Morden Posted April 5, 2006 Share Posted April 5, 2006 Holy Sh1t ç.,,ç Yup, religion puts a stop to many things - threads, rational free thought, lives, childhood innocence, ancient civilisations, good rock music, staying in bed on whatever is the sabbath, not fearing god, friendships, the attention of others, ............ If you look back, most threads that stop suddenly, rather than run out of steam naturally, are the ones where some member adds a thread that includes one or more of the following: 1. Objectivity. 2. Common sense. 3. Balanced opinion. 4. Reason. 5. Suggesting that the answer to violent crime may not be violent mob punishment. 6. At certain times of the day, sobriety. I hate people who do that. They should be strung up and shot. But, you know, the real mystery is those new threads that you known you saw earlier but can't find again. Where do they go?

Morden Posted April 5, 2006 Share Posted April 5, 2006 Yep, that'll work Tax. Ahhhh... but it didn't in this case did it ?? totster But you might have done it. Darn!! Might as well continue then. What's bound to keep a thread going, but not necessarily on topic? Threads that include one or more of the following: 1. Off topic remarks. 2. Personal attacks. 3. Criticism of a poster's spelling, grammar or girlfriend. 4. Comments about gut-bucket farangs. 5. Comments about old farangs. 6. Comments about bg's. 7. Questions about the best way to own land in LOS even though the law says you can't. Yes, you don't have to kill a thread stone dead. You can torture it a bit first - provided that you fly it to a country where that's allowed. Link to comment Share on other sites More sharing options...
Kerryd Posted April 5, 2006 Share Posted April 5, 2006 Yep, that'll work Tax. Ahhhh... but it didn't in this case did it ?? totster Ahhh, but if that had been posted in a thread related to that subject, it quite likely would have ended any further discussion. I was a bit annoyed a few times when I spent a lot of time and effort to compose a well thought-out, comprehensive response to a thread, only to see that no one ever replied afterwards. Where the points I brought up that good that no one could counter them ? Was the post so long-winded that people gave up on it, or forgot why they were there in the first place (like tax's example above) ? Did I just happen to add my response at the time when everyone else had already had their say, and were no longer interested in the subject ? Maybe it has something to do with people seeing who had the last post in the subject, and not wanting to read anything that person has to say ? Maybe a butterfly flapped it's wings in South America, at the same time as you posted your reply, and the chaos theory aspect of that action resulted in that thread being killed ? Or maybe some "Intelligent Designer" decided that the thread was no longer pertinent and has turned everyone's attention to different matters.

I was a bit annoyed a few times when I spent a lot of time and effort to compose a well thought-out, comprehensive response to a thread, only to see that no one ever replied afterwards. Could be. Where the points I brought up that good that no one could counter them ?

Did I just happen to add my response at the time when everyone else had already had their say, and were no longer interested in the subject ? Some people are just one shot deals. Maybe it has something to do with people seeing who had the last post in the subject, and not wanting to read anything that person has to say ? I hope not, I though some people liked me here. Maybe a butterfly flapped it's wings in South America, at the same time as you posted your reply, and the chaos theory aspect of that action resulted in that thread being killed ? Is that where he is? I thought he was in France. Or maybe some "Intelligent Designer" decided that the thread was no longer pertinent and has turned everyone's attention to different matters. That's the one I would vote for. Edited April 5, 2006 by thaibebop Link to comment Share on other sites More sharing options...
