Transitive Closure Logic and Multihead Automata with Nested Pebbles
… extensions of first-order logic are studied in descriptive complexity theory. These extensions include transitive closure logic and deterministic transitive closure logic, which extend first-order logic with transitive closure operators. It is known that deterministic transitive closure logic …

Game comonads and beyond: compositional constructions for logic and algorithms
… theoretic methods to the fields of finite model theory and descriptive complexity. First introduced by Abramsky, Dawar and Wang in 2017, these new constructions exposed connections between Spoiler-Duplicator games used in logic, related algorithms for constraint satisfaction and structure …
