GEOMETRIC DECOMPOSITIONS, ALGEBRAIC MODELS AND RIGIDITY THEOREMS

[摘要] We explore the (co)formality and (co)spherical generation of a space and the relationship between them. As a consequence of general rigidity results we obtain a linear obstruction theory for these properties. We also show that the skeletal versions of these properties are in fact characterized by this linearization.
