Abstract:
We consider facets of Klein polyhedra of a given integer-linear type T in a certain lattice. Let ET(N,s) be the typical number of facets, averaged over all integral s-dimensional lattices with determinant N. Assume that the interior of any facet of type T contains at least one point of the corresponding lattice. We prove that
ET(N,s)=CTlns−1N+OT(lns−2N⋅lnlnN)as N→∞,
where CT is a positive constant depending only on T.
