The advent of computer-supported collaborative work (CSCW) systems significantly impacts group collaboration. This paper reviews three CSCW systems: Lotus Notes, Xerox DocuShare, ...
Abstract. We give a classification of all equivelar polyhedral maps on the torus. In particular, we classify all triangulations and quadrangulations of the torus admitting a vertex...
We propose a 2-party UC-secure protocol that can compute any function securely. The protocol requires only two messages, communication that is poly-logarithmic in the size of the ...
The lifting of results from factor groups to the full group is a standard technique for solvable groups. This paper shows how to utilize this approach in the case of non-solvable n...
