The
Introduction to Calabi-Yau
manifolds and Conifold Transitions
2:00 – 3:00pm
Abstract
We will start from the basic
differential geometry of Calabi-Yau manifolds and
work up to show a number of ways of constructing both compact and non-compact
examples. We then turn to a brief discussion on isolated conical singularities
of Calabi-Yau manifolds and their local geometry. In particular,
the conifold singularity appears frequently in string
theory, and the topology near the conifold
singularity can undergo a topological transition. We shall focus on a
well-known example given by Candelas and de la Ossa.

From Characteristic p > 0
to Characteristic 0
3:00 – 4:00pm
Abstract
In this
talk, I will introduce a few well-known examples and open questions in
algebraic geometry, where a problem of Characteristic zero can be solved by positive
characteristic method.
Refreshments will be available from 1:45pm
