Title ：Physics and algebraic topology

Abstract：Although we often talk about the "unreasonable effectiveness
of mathematics in the natural sciences", there are great disparities in
the relevance of various subbranches of mathematics to individual fields
of natural sciences. Algebraic topology was a subject whose influence to
physics remained relatively minor for a long time, but in the last
several years, theoretical physicists started to appreciate the
effectiveness of algebraic topology more seriously. For example, there
is now a general consensus that the classification of the symmetry-
protected topological phases, which form a class of phases of matter
with a certain particularly simple property, is done in terms of
generalized cohomology theories.

In this talk, I would like to provide a historical overview of the use
of algebraic topology in physics, emphasizing a few highlights along the
way. If the time allows, I would also like to report my struggle to
understand the anomaly of heterotic strings, using the theory of
topological modular forms.
