Marina Ratner's work: from butterflies and shearing, to rigidity

What does 'shearing' has to with butterflies?  What does 'rigidity' means in mathematics and why is it important? In this talk, accessible to Bachelor and Master students with a mathematical background, we will try to answer these questions offering a glimpse of the powerful mathematical works of Marina Ratner (1938-2017) and her legacy, from the Ratner shearing property to Ratner's rigidity theorems.

The talk is part of the May12 initiatives to 'Celebrate Women in Mathematics'.
