Are there examples of compact connected matrix groups other than the product of SO(n), Sp(n), U(n) and the exceptional groups.

In 1958 I.N.Baker proved in , that the powerseries for fractional iterates of the function exp(x)-1 have convergence-radius zero. P.Erdös / E.Jabotinsky followed in with the...

Dear All, I have an interesting problem here. I am not sure if I have posted this question before, but have had no responses so far and so trying again. My problem is...

Hello, all! My thesis involves working with the classifying space of the Poincare group, P. For those of you not familiar with the Poincare group, here is a reference:...

Is it of interest to know that two permutations of order 2 cannot generate the symmetric group Sn for values n3? Has this already been proven?

I am wondering if someone can point me to a reference with explicit formulas for the eigenvalues and more importantly eigenvectors of perfectly balanaced binary...

Dear Everybody, Please kindly help me in a problem that I am trying to understand here. My research problem that I have to solve is: I have a sequence of million elements....

On several occasions I have had the following experience. There is some math book that I consult frequently enough that I decide it would be nice to have a copy. The book...

Dear all, I am sending you the table of contents for the July 2008 issue of Statistica Sinica. In this issue, we have a collection of seven articles on the theme topic of ...

Dear fellow researchers, Does anyone know the answer (or any relevant reference) to the following question: Let C be a closed pointed convex cone in some finite...

Hi everyone, I've come up with a simple way to "derive" Gauss's prime density function using probability heuristics, alone. The "derivation" involves setting up a nonlinear...

Dear all, Statistica Sinica is announcing a call for discussion on the following paper: "INTRINSIC SHAPE ANALYSIS: GEODESIC PCA FOR RIEMANNIAN MANIFOLDS MODULO ISOMETRIC...

Dear s.m.r, I'm currently working on a problem that gives me a bit of a headache. I have a 'particle' in R^n following the stochastic differential equation d/dt x(t) ==...

Is an asymptotic formula known for the fraction of polynomials (monic with integer coefficients) that are irreducible? I need to specify a way of going to infinity here, so...

Some of the classical triangle centers can be expressed as solutions to optimization problems: Given a triangle A_1, A_2, A_3, define d_i (i=1,2,3) to be the distance of a...
