Realizability of Concurrent Recursive Programs
Abstract. We define and study an automata model of concurrent recursive programs. An automaton consists of a finite number of pushdown systems running in parallel and communicati...

Emptiness of Multi-pushdown Automata Is 2ETIME-Complete
We consider multi-pushdown automata, a multi-stack extension of pushdown automata that comes with a constraint on stack operations: a pop can only be performed on the first non-emp...

Boolean algebras of unambiguous context-free languages
Several recent works have studied subfamilies of deterministic context-free languages with good closure properties, for instance the families of input-driven or visibly pushdown la...

Minimization, Learning, and Conformance Testing of Boolean Programs
Boolean programs with recursion are convenient abstractions of sequential imperative programs, and can be represented as recursive state machines (RSMs) or pushdown automata. Motiv...

The role of information in the cop-robber game
We investigate the role of the information available to the players on the outcome of the cops and robbers game. This game takes place on a graph and players move along the edges ...
