Question for mathematics researchers My question is a survey question for professionals and amateurs who do research in mathematics: What motivates you to do mathematics research and what are the goals of your research? Craig ... 21 Jul 2010 21:19
Cumulative distribution function for variance gamma process Does anyone have any references or knowledge on the cdf for a variance gamma process? I understand that the integral doesn't have a closed form, but what can be said about the practical issues of ensuring a workable numerical integration procedure with reasonable accuracy and efficiency? I have scoured a lot of... 20 Jul 2010 20:11
Numerical Derivative Help.. Hello everyone! this is my first message, i am having a problem with numerical derivative, which i think is related to logarithm issues. I have a set of points (v,Z(v)) which i call them the Z function. for example: Z(v): http://dl.dropbox.com/u/6380744/img/zfunction.png from Z, i can get U. U(v) = (1... 21 Jul 2010 19:08
game theory, markov perfect equilibria hello! does anybody of you know of some graphical illustration of a markov perfect equilibrium. i imagine something like these extensive form illustrations. i would need this for my thesis to explain the finding of equilibria in no-commitment settings in optimal policy model. i am grateful for every hint! t... 22 Jul 2010 20:14

Small Universe Theory Here is a wacky theory that I though of a few years ago. Small Universe Theory Hypotheses 1) Our universe can be simulated by running a program on a super big computer. 2) That program is among the shortest programs that can simulate intelligent life. Supposing that 1) and 2) are true, I think it might... 20 Jul 2010 19:05
