## Abstract In this paper we study a generalized symplectic fixed‐point problem, first considered by J. Moser in [20], from the point of view of some relatively recently discovered symplectic rigidity phenomena. This problem has interesting applications concerning global perturbations of Hamiltonia
All 3-dimensional convex polytopes are known to be rigid. Still their Minkowski di¬erences (virtual polytopes) can be ®exible with any nite freedom degree. We derive some su¯cient rigidity conditions for virtual polytopes and present some examples of ®exible ones. For example, Bricard's rst and seco
