Regular Languages of Nested Words: Fixed Points, Automata, and Synchronization
Abstract. Nested words are a restriction of the class of visibly pushdown languages that provide a natural model of runs of programs with recursive procedure calls. The usual conne...

Model Checking Freeze LTL over One-Counter Automata
We study complexity issues related to the model-checking problem for LTL with registers (a.k.a. freeze LTL) over one-counter automata. We consider several classes of one-counter au...

Reducing the Size of NFAs by Using Equivalences and Preorders
Abstract. The efficiency of regular expression matching algorithms depends very much on the size of the nondeterministic finite automata (NFA) obtained from regular expressions. R...

Heredity, Complexity, and Surprise: Embedded Self-Replication and Evolution in CA
Abstract. This paper reviews the history of embedded, evolvable selfreplicating structures implemented as cellular automata systems. We relate recent advances in this field to the...

Traces of I/O-Automata in Isabelle/HOLCF
Abstract. This paper presents a formalization of nite and in nite sequences in domain theory carried out in the theorem prover Isabelle. The results are used to model the metatheor...
