The finite model theory toolbox of a database theoretician
For many years, finite model theory was viewed as the backbone of database theory, and database theory in turn supplied finite model theory with key motivations and problems. By n...

Automata and Logics for Words and Trees over an Infinite Alphabet
In a data word or a data tree each position carries a label from a finite alphabet and a data value from some infinite domain. These models have been considered in the realm of sem...

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...

Whirlpool PLAs: a regular logic structure and their synthesis
 A regular circuit structure called a Whirlpool PLA (WPLA) is proposed. It is suitable for the implementation of finite state machines as well as combinational logic. A WPLA is ...

Properties of logics of individual and group agency
We provide proof-theoretic results about deliberative STIT logic. First we present STIT logic for individual agents without time, where the problem of satisfiability has recently b...
