Euler bricks {a,b,c} and Euler quadruples {a,b,c,d}
Hello all, I. The "Euler brick" is well-known. These are triples (a,b,c) such that, a^2+b^2 = x^2 a^2+c^2 = y^2 b^2+c^2 = z^2 all in positive integers. II. Euler also considered quadruples (a,b,c,d) such that, a^2+b^2+c^2 = x^2 a^2+b^2+d^2 = y^2 a^2+c^2+d^2 = z^2 b^2+c^2+d^2 = t^2 Interestingly,... 13 Aug 2010 16:52

Linear program with higher order non-linear constaints???
Hi, I am not sure whether I have posted the question on the right place or not as I was unable to find the optimization forum. I want to solve a linear objective function, with some linear constraints and one higher order non-linear (not quadratic, it Lp-norm) constraint. I know that Lp-norm constraint can be ... 13 Aug 2010 15:46
statistical tests for random number generators
This thread is intended for discussion of statistical tests for random number generators and software packages that include such tests.

abramowitz book, is it still relevant to today's needs?
I checked the last printing of Abramowitz and Stegun's handbook of mathematical functions, with formulas, graphs and mathematical table; the last printing, the 10th precisely, was in 1972. Is the handbook still relevant or can i get something better for mathematical formulas, graphs and tables? xnt -- h... 13 Aug 2010 12:30

uniform convergence - on compacta
Suppose f is continuous and vanishes at infinity. Suppose you know that |(g_k)f - f| --> 0 in the SUP norm for k going to infinity (g_k are infinitely differentiable compactly supported functions with support on the ball of radius K centered in the origin and such that g_k(x)=1 if x belongs to the the previousl... 13 Aug 2010 11:24
