We describe an algorithm for computing a finite, and typically small, presentation of the fundamental group of a finite regular CW-space. The algorithm is based on the constructi...

The present paper investigates properties of quasi stable ideals and of Borel-fixed ideals in a polynomial ring k[x0, . . . , xn], in order to design two algorithms: the first on...
The Rabin scheme used in public-key cryptosystem is here revisited with a focus limited to a few specific open issues. In particular, message decryption requires one out of four ...
