The breadth of Berikashvili's functor D
Johannes Huebschmann
We discuss variants of Berikashvili's functor that arise in differential homological algebra, from simplicial bundles, from ordinary topological bundles, and in more general catego…
Crossed modules
Johannes Huebschmann
This is an overview of the idea of a crossed module. For a group, the triple that consists of the group, its group of automorphisms, and the canonical homomorphism from the group t…
Classical phase space singularities and quantization
Johannes Huebschmann
Simple classical mechanical systems and solution spaces of classical field theories involve singularities. In certain situations these singularities can be understood in terms of s…
Minimal free multi models for chain algebras
Johannes Huebschmann
Let R be a local ring and A a connected differential graded algebra over R which is free as a graded R-module. Using homological perturbation theory techniques, we construct a mini…
