: We investigate context-free languages with respect to the measure Var of descriptional complexity, which gives the minimal number of nonterminals which is necessary to generate t...
Quantitative properties of timed regular languages, such as information content (growth rate, entropy) are explored. The approach suggested by the same authors is extended to lang...
In this paper, we introduce block insertion and deletion on trajectories, which provide us with a new framework to study properties of language operations. With the parallel synta...
Abstract. Some decision problems related to balanced context-free languages are important for their application to the static analysis of programs generating XML strings. One such ...
Several proposals for updating XML have been introduced. Many of them have a rather complicated semantics due to the interaction of side-effects and updates, and some proposals a...
