On applications of homogeneous structures in computer science Bodirsky, Manuel
Description
Homogeneous structures and their reducts have been used as templates of Constraint Satisfaction Problems (CSPs) to model qualitative reasoning problems in Artificial Intelligence. But this is not the only context in which homogeneous structures arise naturally in CS; we will discuss more recent links between homogeneous structures and permutation pattern avoidance classes, and between homogeneous structures and automata theory (for data word languages). I will present a fragment of existential second-order logic such that the queries that can be formulated in this logic describe (finite unions of) CSPs for reducts of homogeneous structures. This logic is quite powerful and contains MMSNP and most CSPs that have been studied in temporal and spatial reasoning.

Homogeneous structures and their reducts have been used
as templates of Constraint Satisfaction Problems (CSPs) to model
qualitative reasoning problems in Artificial Intelligence.
But this is not the only context in which homogeneous structures arise naturally in CS;
we will discuss more recent links
between homogeneous structures and permutation pattern avoidance classes,
and between homogeneous structures and automata theory (for data word languages).
I will present a fragment of existential second-order logic
such that the queries that can be formulated in this logic describe (finite unions of) CSPs
for reducts of homogeneous structures. This logic is quite powerful and contains
MMSNP and most CSPs that have been studied in temporal and spatial reasoning.
