Title:Elementary surprises in projective geometry
Seminar:Center for Dynamics and Geometry Seminars
Speaker:S. Tabachnikov, Penn State
Abstract:
Jointly with R. Schwartz, we have recently discovered eight new (?) configuration theorems of projective geometry, somewhat similar to the classical Pappus and Pascal theorems. These theorems involve n-gons with n from six to twelve. I shall describe these results and illustrate them by computer graphics. I shalll explain how they originated in our study of the pentagram map, a completely integrable system on the moduli space of polygons in the projective plane.
