Differential Operator Endomorphisms of an Euler-Lagrange Complex
Martin Markl, Steve Shnider
The main results of our paper deal with the lifting problem for multilinear differential operators between complexes of horizontal de Rham forms on the infinite jet bundle. We answ…

Invariant quantization in one and two parameters on semisimple coadjoint orbits of simple Lie groups
Joseph Donin, Dmitry Gurevich, Steve Shnider
We study one and two parameter quantizations of the function algebra on a semisimple orbit in the coadjoint representation of a simple Lie group subject to the condition that the m…

Coherence Constraints for Operads, Categories and Algebras
Martin Markl, Steve Shnider
Coherence phenomena appear in two different situations. In the context of category theory the term `coherence constraints' refers to a set of diagrams whose commutativity implies t…
