Pure Maths Colloquium: Toric singularities of surfaces in terms of lattice trigonometry.

Presented by Oleg Karpenkov, University of Liverpool

20 October 2014 16:00 in CM221

Continued fractions plays an important role in lattice trigonometry. From one hand this subject is a natural and therefore interesting to be considered by itself. From the other hand lattice trigonometry helps to describe singularities of toric varieties (which gives first results toward the solution of so-called "IKEA problem"). In this talk I will give a general introduction to the subject with various examples. I will try to avoid complicated technical details explaining main ideas behind them.
