The Design of ESSENCE: A Constraint Language for Specifying Combinatorial Problems
ESSENCE is a new formal language for specifying combinatorial problems in a manner similar to natural rigorous specifications that use a mixture of natural language and discrete ...

Tabloids and weighted sums of characters of certain modules of the symmetric groups
We consider certain modules of the symmetric groups whose basis elements are called tabloids. As modules of the symmetric groups, some of these are isomorphic to Springer modules. ...

Threshold arrangements and the knapsack problem
We show that a combinatorial question which has been studied in connection with lower bounds for the knapsack problem by Brimkov and Dantchev (2001) is related to threshold graphs...

The method of combinatorial telescoping
We present a method for proving q-series identities by combinatorial telescoping in the sense that one can transform a bijection or classification of combinatorial objects into a ...
