Title: Asymptotic behavior of Integer Programming and the stability of the
Castelnuovo-Mumford regularity.
Abstract: In the talk we explain a connection between Commutative Algebra
and Integer Programming and contains two parts. The first one is devoted
to the asymptotic behavior of integer programs with a fixed cost linear
functional and the constraint sets consisting of a finite system of linear
equations or inequalities with integer coefficients depending linearly on
$n$. An integer $N_*$ is determined such that the optima of these integer
programs are a quasi-linear function of $n$ for all $n\ge N_*$. Using
results in the first part, one can bound in the second part the indices of
stability of the Castelnuovo-Mumford regularities of integral closures of
powers of a monomial ideal and that of symbolic powers of a square-free
monomial ideal.
