Partition identities and the coin exchange problem
The number of partitions of n into parts divisible by a or b equals the number of partitions of n in which each part and each difference of two parts is expressible as a non-negati...

Powers of t-norms
In this paper we consider the rth powers of a continuous t-norm for positive real numbers r, generalizing the notion of the diagonal (2nd power). We identify the increasing functi...

Permutation Patterns and Continued Fractions
We find, in the form of a continued fraction, the generating function for the number of (132)-avoiding permutations that have a given number of (123) patterns, and show how to ext...

The cutoff phenomenon for randomized riffle shuffles
We study the cutoff phenomenon for generalized riffle shuffles where, at each step, the deck of cards is cut into a random number of packs of multinomial sizes which are then riffl...
