We introduce a simply typed λ-calculus λκε which has both contexts and environments as first-class values. In λκε, holes in contexts are represented by ordinary variables ...
In this paper, we show how to obtain causal semantics distinguishing ”earlier than” and ”not later than” causality between events from algebraic semantics of Petri nets. J...
It is a difficult challenge to find Boolean functions used in stream ciphers achieving all of the necessary criteria and the research of such functions has taken a significant d...
We define a class of special function inequalities that contains many classical examples, such as the Cauchy-Schwarz inequality, and introduce a proving procedure based on induct...
Series-parallel orders are de ned as the least class of partial orders containing the one-element order and closed by ordinal sum and disjoint union. From this inductive de nition,...
