Centrality and the KRH Invariant
Louis H Kauffman, David Radford, Stephen Sawin
The purpose of this paper is to discuss the categorical structure for a method of defining quantum invariants of knots, links and three-manifolds. These invariants can be defined i…
Factorials and powers, a minimality result, revisited
David E. Radford
Let . Then for some positive integer . There are several numerical sequences associated with the study of the smallest such integer which are studied in \cite{…
Factorials and powers, a minimality result
David E. Radford
Let . Then for some positive integer . We show that the smallest such is one of a pair of possibilities, or is one possibility, which we show how to calcul…
The gamma function and a certain sequence of differences
David E. Radford
We study a sequence of differences related to the problem of finding the smallest factorial greater than or equal to , where , using the gamma function.
On Automorphisms of Biproducts
David E. Radford
We study certain subgroups of the full group of Hopf algebra automorphisms of a biproduct. In the process interesting subgroups of certain permutation groups come into play.
Biproducts and Kashina's examples
David E. Radford
We revisit a class of examples described in the original paper on biproducts, expand the class, and provide a detailed analysis of the coalgebra and algebra structures of many of t…
