Schaefer's theorem is a complexity classification result for so-called Boolean constraint satisfaction problems: it states that every Boolean constraint satisfaction problem ...
The problem of counting the number of monomer-dimer coverings of a lattice comes from the field of statistical mechanics. It has only been shown to be exactly solved for the speci...

Let Fk(x) = n=0 Fk n xn . Using the interpretation of Fibonacci numbers in the terms of Morse codes, we give a bijective proof of Riordan's formula (1 - Lkx + (-1)k x2 )Fk(x...
We present the verification of a protocol designed to ensure self-stabilization in a ring of processors. The proof is organized as a series of refinements; it is mechanized base...
Abstract. We present an approach to a coherent program synthesis system which integrates a variety of interactively controlled and automated techniques from theorem proving and alg...
