Title: Introduction to mutations of potentials

Date: Jun 8, 2012

Place: Vienna, Nordberggasse

Why we want to study mutations and Laurent phenomenon? One motivation comes from an approach to mirror symmetry: toric degenerations hypothesis after Batyrev, Ciocan-Fontanine, Kim and van Straten; study of open A-model and m_0 potential after Auroux, Hori, SYZ and Auroux's wall-crossing. What is a cluster algebra (after Fomin and Zelevinsky) and an upper bound (same and Berenstein). From toric degenerations to integrable systems. A mysterious relation between closed and open correlators.
