For Matthias Schramm on his sixty-fifth birthday

Dedicated to Professor Olvi Mangasarian on the occasion of his sixty-fifth birthday

In this paper we reformulate several NCP-functions for the nonlinear complementarity problem (NCP) from their merit function forms and study some important properties of these NCP-functions. We point out that some of these NCP-functions have all the nice properties investigated by Chen, Chen and Kanzow [2] for a modified Fischer-Burmeister function, while some other NCP-functions may lose one o...

More on Convolution of Riemannian Manifolds Dedicated to Professor T. Otsuki on his eighty-fifth birthday

In an earlier paper [1], the author introduced the notion of convolution of Riemannian manifolds. In [1] he also provided some examples and applications of convolution manifolds. In this paper we use tensor product to construct more examples of convolution manifolds and investigate fundamental properties of convolution manifolds. In particular, we study the relationship between convolution mani...

A Formalism for the Description of Protein Interaction Dedicated to Jerzy Tiuryn on the Occasion of His Sixty Birthday

The Calculus of Looping Sequences is a formalism for describing evolution of biological systems by means of term rewriting rules. We propose to enrich this calculus by labelling elements of sequences. Since two elements with the same label are considered to be linked, this allows us to represent protein interaction at the domain level. Well-formedness of terms are ensured by both a syntactic co...

Alfred Klemm on his 100th Birthday

After completing my studies in physics at the university in Frankfurt (Diplom), I started my PhD work in the group of Professor Alfred Klemm at the MaxPlanck-Institut für Chemie in Mainz on November 1, 1958. In my thesis, I measured the difference in thermal conductivity between oand p-H2 at 20 K. Alfred Klemm’s main area of research was molten salts; this subject, however, resulted from his co...
