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 $a > 1$ . Then $a^{n} < n!$ for some positive integer $n$ . 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 $a > 1$ . Then $a^{n} < n!$ for some positive integer $n$ . We show that the smallest such $n$ 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 $n!$ greater than or equal to $a^{n}$ , where $a > 1$ , using the gamma function.
