Mathematics Department Colloquium/Serge Lang Undergraduate Lecture: Distinguishing shapes via topology
Lecture | April 18 | 4:10-5 p.m. | 60 Evans Hall
Helene Barcelo, MSRI
Topologists will say that a coffee cup is like a donut. What do they mean? Homotopy and Homology are invariants created to distinguish basic geometric structures. In this talk I will briefly talk about the history of such invariants and describe new ones that are also applicable to discrete structures like graphs.
