Four Approaches to Automated Reasoning with Differential Algebraic Structures
While implementing a proof for the Basic Perturbation Lemma (a central result in Homological Algebra) in the theorem prover Isabelle one faces problems such as the implementation o...

The Logical Role of the Four-Valued Bilattice
In his well-known paper \How computer should think" ( Be77b]) Belnap argues that four-valued semantics is a very suitable setting for computerized reasoning. In this paper we...

The Complexity of Positive First-Order Logic without Equality II: The Four-Element Case
We study the complexity of evaluating positive equality-free sentences of first-order (FO) logic over fixed, finite structures B. This may be seen as a natural generalisation of th...

Algebraic Structures for Bipolar Constraint-Based Reasoning
The representation of both scales of cost and scales of benefit is very natural in a decision-making problem: scales of evaluation of decisions are often bipolar. The aim of this ...
