Alexander Borst studied Biology at the University of Wuerzburg. His PhD work in Martin Heisenberg’s lab demonstrated that the mushroom bodies of Drosophila are indispensable for olfactory learning. He did a postdoc with Karl Goetz at the Max-PlanckInstitute for biological Cybernetics in Tübingen, where he started to work on fly motion vision, a field which he never left since. In 1993, he becam...

Confirmatory, deductive research cannot produce absolute truths, according Karl POPPER (2002). If we accept this premise, then it is worth giving inductive and explorative research another chance. Exploration can produce valid and insightful findings in the social sciences, if conducted in a transparent and self-reflexive way. It can also profit from applying dialectical thinking. This article ...

The interest in polygon decomposition emanates from the theoretical importance of the problem on one hand and the many applications that it has on the other. The decomposition problem has been extensively studied in the literature and yet variations of the problem remain open [3]. The existence of a huge literature on this problem can be informally explained by the fact that there are numerous ...

In this paper we present the language G-KARL. G-KARL allows to describe the static, the functional and the dynamic view to a knowledge based system (kbs) graphically. This graphical representation makes the communication between the expert and the knowledge engineer easier. The underlying conceptual model for G-KARL is derived from the KADS model of expertise. Every primitive of G-KARL may be m...

We study a family of subvarieties of the flag variety defined by certain linear conditions, called Hessenberg varieties. We compare them to Schubert varieties. We prove that some Schubert varieties can be realized as Hessenberg varieties and vice versa. Our proof explicitly identifies these Schubert varieties by their permutation and computes their dimension. We use this to answer an open quest...
