Mixed spaceform problems in topology ask for characterizations of the fundamental groups of manifolds whose universal cover is homotopy finite, especially if the universal cover is a product (Nⁿ ×\Bbb R^k) / \Gamma. Existential results and some characterization theorems are presented. Fundamental groups \Gamma of closed mixed spaceforms are found to be virtual Poincaré duality groups if some finiteness conditions are satisfied.
