From Bidirectionality to Alternation
We describe an explicit simulation of 2-way nondeterministic automata by 1-way alternating automata with quadratic blow-up. We first describe the construction for automata on fin...

The Weakness of Self-Complementation
Model checking is a method for the verification of systems with respect to their specifications. Symbolic model-checking, which enables the verification of large systems, procee...

Factorisation Forests for Infinite Words
The theorem of factorisation forests shows the existence of nested factorisations -- a la Ramsey -- for finite words. This theorem has important applications in semigroup theory, a...

Tight Upper Bounds for Streett and Parity Complementation
Complementation of finite automata on infinite words is not only a fundamental problem in automata theory, but also serves as a cornerstone for solving numerous decision problem...

Variable Automata over Infinite Alphabets
Automated reasoning about systems with infinite domains requires an extension of regular automata to infinite alphabets. Existing formalisms of such automata cope with the infinite...
