Abstract: Mirror symmetry has been a driving force in geometry and physics
for twenty years. Recently, there are some surprising developments in
connection to number theory. The center of attention is the so called the
modular form, a central topic in number theory. Traditionally, we apply
mirror symmetry to map a difficult problem to an easy problem. The recent
advance on the modular form requires a join force from both sides of
mirror symmetry. In the talk, I will explain these exciting developments.
