Separation of operators
Sammanfattning: Separable Hilbert spaces are familiar to those who have been taught functional analysis, and separation of variables in differential equationes is a standard tool being researched here at the Mathematics Department. I will here introduce another notion of separability, relevant for positive operators with trace one (e.g., quantum-mechanical "states"), and some criteria to determine separability. Among other things, the difference between positive maps and completely positive maps will be important in this context.

Möbius mushrooms and other complex organisms
Sammanfattning: One of the more intriguing questions in embryology is how we, from one uniform egg, through successive cell-divisions, become those complex creatures we are. This riddle has engaged people for centuries. Today, when we are faced with overwhelming genetic information, we are mainly intrigued by the question how this DNA-code is realized into a developing organism.
In the colloquium, we are going to look at a few embryonic developments, and a couple of mathematical models which are used today in morphogenesis (a term which was introduced by Goethe when he was studying how biological organisms got their shape). We will also speculate if some other mathematical tools could be useful in the study of morphogenesis, such as Möbius mappings.
