Abstract. The main result is that for every recursively enumerable existential consistent theory (in the usual language of group theory), there exists a finitely presented SQ-univ...
We show that certain finite groups do not arise as the automorphism group of the square of a finite algebraic structure, nor as the automorphism group of a finite, 2-generated, ...
Many emerging applications in both wired and wireless networks need support of secure group communications. There have been many secure group communication schemes in the setting ...
