The probability that a random monic p-adic polynomial splits into linear factors
Joe Buhler, Daniel Goldstein, David Moews +1
Let n be a positive integer and let p be a prime. We calculate the probability that a random monic polynomial of degree n with coefficients in the ring Z_p of p-adic integers split…

Inequalities for finite group permutation modules
Daniel Goldstein, Robert M. Guralnick, I. M. Isaacs
If f is a nonzero complex-valued function defined on a finite abelian group A and \hat f is its Fourier transform, then |Supp (f)||Supp {\hat f)| \ge |A|, where Supp (f) and Supp (…
