2-categories and cyclic homology

Slevin, Paul (2016) 2-categories and cyclic homology. PhD thesis, University of Glasgow.

Abstract

The topic of this thesis is the application of distributive laws between comonads to the theory of cyclic homology. The work herein is based on the three papers 'Cyclic homology arising from adjunctions', 'Factorisations of distributive laws', and 'Hochschild homology, lax codescent,and duplicial structure', to which the current author has contributed. Explicitly, our main aims are:

1) To study how the cyclic homology of associative algebras and of Hopf algebras in the original sense of Connes and Moscovici arises from a distributive law, and to clarify the role of different notions of bimonad in this generalisation.
2) To extend the procedure of twisting the cyclic homology of a unital associative algebra to any duplicial object defined by a distributive law.
3) To study the universality of Bohm and Stefan’s approach to constructing duplicial objects, which we do in terms of a 2-categorical generalisation of Hochschild (co)homology.
4) To characterise those categories whose nerve admits a duplicial structure.
