[Facets-of-complexity] talk by Daniel Huson on periodic tilings, Friday Nov. 23 in Potsdam/Golm

[Günter Rote <rote@inf.fu-berlin.de>]

Dear Facets! Tomorrow there will be a lecture that might be interesting 
to some of us. (Beware: it is in Golm behind Potsdam; it takes a while 
to get there.)

On 24.11, at 10:00 am, there will be a talk by Prof. Daniel Huson, 
University of Tübingen:

A galaxy of periodic tilings

This talk has four parts. In the first part - topology -, we recall the
classification of two dimensions manifolds and orbifolds, and introduce
their Conway notation. In the second part - geometry -, we discuss
two-dimensional periodic tilings and their classification. In the third
part - combinatorics -, we introduce Delaney-Dress symbols and indicate
how they can be used to systematically enumerate periodic tilings.
Finally, in the fourth part - algorithms and software -, we present
Tegula (http://tegula.husonlab.org), a new computer program that can
be used the explore the “galaxy” of all 2.4 billion periodic tilings
of the euclidean plane, sphere and hyperbolic plane, of low
Dress-complexity.
This is joint work with Olaf Delgado and Rüdiger Zeller.

It will take place in House 9 of the Golm Campus at the
University of Potsdam. Room 1.22
