    In this paper, we prove that the two avours of well-compo- sedness called Continuous Well-Composedness (shortly CWCness), stat- ing that the boundary of the continuous analog of a discrete set is a manifold, and Digital Well-Composedness (shortly DWCness), stating that ...

    A transition in a graph is a pair of adjacent edges. Given a graph $$G=V,E$$, a set of forbidden transitions $$\mathcal{F}\subseteq E\times E$$ and two vertices $$s,t \in V$$, we study the problem of finding a path from s to t which uses none of the forbidden transition...

    Abstract - We construct new functional encryption schemes that combine the access control functionality of attribute based encryption with the possibility of performing linear operations on the encrypted data. While such a primitive could be easily realized from fully f...
