The Hopf Algebra of Rooted Trees, Free Lie Algebras, and Lie Series
We present an approach that allows performing computations related to the Baker-Campbell-Haussdorff (BCH) formula and its generalizations in an arbitrary Hall basis, using labeled...

Interpreted Trajectories
Abstract. We introduce generalized trajectories where the individual symbols are interpreted as operations performed on the operand words. The various previously considered traject...

Spatial reasoning under imprecision using fuzzy set theory, formal logics and mathematical morphology
In spatial reasoning, in particular for applications in image understanding, structure recognition and computer vision, a lot of attention has to be paid to spatial relationships ...

Combinatorial Properties of Sturmian Palindromes
We study some structural and combinatorial properties of Sturmian palindromes, i.e., palindromic finite factors of Sturmian words. In particular, we give a formula which permits t...

A Discrete-Event Approach to Transcription Control with Dynamic Event-Controllability
This paper presents a discrete-event approach to synthesis of transcription control for a class of (computational) gene networks. Given a set of genes and protein-gene and/or prote...
