Let M be a noncompact 4-manifold with at least two open ends. Suppose that one of these ends is homeomorphic to N x iI& where N is an oriented 3-manifold satisfying one of the following conditions: (i) ~1 (N) is an extension of the free group by a perfect normal subgroup. (ii) HI (N) g Z/n, @. @ Z
The Euler equation and the DehnαSommerville equations are known to be the Ε½ . Ε½ only rational linear conditions for f-vectors number of simplices at various . dimensions of triangulations of spheres. We generalize this fact to arbitrary triangulations, linear triangulations of manifolds, and polytop
