## Donaldson-Thomas and Gromov-Witten theory of orbifolds and their resolutions

Topic:

A general principle in physics asserts that string theory on a

Calabi-Yau orbifold should be equivalent to string theory on any

Calabi-Yau resolution of the orbifold. A mathematical realization of

this principle is the idea that Donaldson-Thomas theory or

Gromov-Witten theory of the orbifold should be equivalent to the

corresponding theory on the resolution. We will discuss these ideas in

general and for some specific examples.
