Origins and breadth of the theory of higher homotopies
Johannes Huebschmann
Higher homotopies are nowadays playing a prominent role in mathematics as well as in certain branches of theoretical physics. We recall some of the connections between the past and…
The sh-Lie algebra perturbation Lemma
Johannes Huebschmann
Let R be a commutative ring which contains the rationals as a subring and let g be a chain complex. Suppose given an sh-Lie algebra structure on g, that is, a coalgebra perturbatio…
The Lie algebra perturbation lemma
Johannes Huebschmann
Let g be a differential graded Lie algebra and suppose given a contraction of chain complexes of g onto a general chain complex M. We show that the data determine an sh-Lie algebra…
A gauge model for quantum mechanics on a stratified space
J. Huebschmann, G. Rudolph, M. Schmidt
In the Hamiltonian approach on a single spatial plaquette, we construct a quantum (lattice) gauge theory which incorporates the classical singularities. The reduced phase space is…
