Abstract
We discuss the problem of counting vertices in Gelfand–Zetlin polytopes. Namely, we deduce a partial differential equation with constant coefficients on the exponential generating function for these numbers. For some particular classes of Gelfand–Zetlin polytopes, the number of vertices can be given by explicit formulas.
