The theory of linear codes over finite fields has long been strengthened by combinatorial theory, and matroid theory has shown to be particularly well suited for providing a theoretical foundation for these codes. Complete descriptions have been...

The canonical commutation relations (CCR's) are at the foundation of quantum mechanics and quantum field theory. To properly analyse the CCR's, which involve unbounded operators, we encode them in a C$^*$-algebra. This C*-algebra however, is not...

In the counting constraint satisfaction problem (#CSP), we wish to know how  many ways there are to satisfy a given system of constraints on a set of variables, where a constraint is  a relation chosen from a fixed finite set. This...
