On a parametrization of positive semidefinite matrices with zeros
parametrization positive semidefinite matrices zeros
2010/3/9
We study a class of parametrizations of convex cones of positive
semidefinite matrices with prescribed zeros. Each such cone corresponds to
a graph whose non-edges determine the prescribed zeros. Ea...
The expected number of zeros of a random system of p-adic polynomials
co-area formula Kac-Rice formula localfield Gaussian q-binomial formula

We study the simultaneous zeros of a random family of d polynomials in d variables over the p-adic numbers.For a family of natural models, we obtain an explicit constant for the expected number of zer...

Measures with zeros in the inverse of their moment matrix
Moment matrix orthogonal polynomials

We investigate and discuss when the inverse of a multivariate
truncated moment matrix of a measure μ has zeros in some prescribed
entries. We describe precisely which pattern of these zeroes
