Title:Ramification Conjecture
Seminar:Center for Dynamics and Geometry Seminars
Speaker:Anton Petrunin, Penn State
This is a work in progress joint with D. Panov. Ramification of polyhedral space is defined as its universal cover which branching in its singular set. We conjecture that the ramification of polyhedral space with nonnegative curvature has nonpositive curvature. This conjecture is closely related to the questions on complex hyperplane arrangements. The conjecture proved two cases (A) 3D-case and (B) 4D-case with complex structure.
