We study logical principles connecting two relations: independence, which is known as nondeducibility in the study of information flow, and functional dependence. Two different e...

In connection with machine arithmetic, we are interested in systems of constraints of the form x + k y + k . Over integers, the satisfiability problem for such systems is polynomi...
We study the algebraic structure of directed bigraphs, a bigraphical model of computations with locations, connections and resources previously introduced as a unifying generaliza...
A general method for finding elementary abelian regular covering projections of finite connected graphs is applied to the Petersen graph. As a result, a complete list of pairwise ...
A new semantics is presented for the logic of proofs (LP), [1, 2], based on the intuition that it is a logic of explicit knowledge. This semantics is used to give new proofs of se...
