00925njm 22002777a 4500 dc Habib, Georges author Richardson, Ken author Centre de Recerca Matemàtica author 2010 We define a new version of the exterior derivative on the basic forms of a Riemannian foliation to obtain a new form of basic cohomology that satisfies Poincaré duality in the transversally orientable case. We use this twisted basic cohomology to show relationships between curvature, tautness, and vanishing of the basic Euler characteristic and basic signature.
