ABSTRACT: In many cases, a crepant resolution of $\mathbb{C}^3/G$, where
$G$ is a finite subgroup of  $SL(3,\mathbb{C})$, happens to be the total
space of the canonical bundle over a Kahler manifold of complex
dimension $2$. Since any such crepant resolution is a noncompact
Calabi-Yau, there is a natural question of constructing a Ricci-flat
metric on it. The existence of such metrics was proven by Joyce. In this
talk, I will show how to construct a Ricci-flat metric when a crepant
resolution is a space $X=tot(K_{M})$, where $K_{M}$ is the canonical
bundle over a 2-dimensional Kahler manifold $M$. 

Best regards,
