The Department of Mathematics will hold a colloquium, “Quantitative Topology?” at 4:10 p.m. on Wednesday, April 18, in Room 204, Ritter Hall.
Shmuel Weinberger, Ph.D., of the University of Chicago, will present.
Topology is known for its reasoning about qualitative features of spaces, and as a subject, it contains many nonconstructive existence proofs. A movie was made of one of these: Smale's theorem that the 2-sphere can be turned inside out. Weinberger will describe some progress towards understanding what the complexity of some of the other objects and maps that we have never yet seen.
Tea will be available at 3:30pm in the lobby of Ritter Hall, with the talk to follow.
