An extended logic programming language embodying sets is developed in successive stages, introducing at each stage simple set dictions and operations, and discussing their operati...

Set functions appear as a useful tool in many areas of decision making and operations research, and several linear invertible transformations have been introduced for set function...
In this paper we prove three theorems about the theory of Borel sets in models of ZF without any form of the axiom of choice. We prove that if B ⊆ 2ω is a Gδσ-set then either...
We provide an explicit construction for a complete set of orthogonal primitive idempotents of finite group algebras over nilpotent groups. Furthermore, we give a complete set of ...
Let P be the ordered set of isomorphism types of finite ordered sets (posets), where the ordering is by embeddability. We study first-order definability in this ordered set. We ...
