A perspective projection of a dodecahedral tessellation in H3. Four dodecahedra meet at each edge, and eight meet at each vertex, like the cubes of a cubic tessellation in E3.

Title: Blowing down and Introduction to MMP

Speaker: Roktim Mascharak

Abstract: Blowing Up is the most basic ( yet one of the most important ) Birational Transform for Algebraic Varieties. But what about the opposite ? Can we investigate if  a smooth variety is blow up of some other smooth variety? With this question in mind we will dive into the Birational classification of smooth projective algebraic varieties and we will introduce the three magical letters, the MMP!! If time permits we will try to take a look at the larger picture and the general philosophy for projective varieties of arbitrary dimensions.

Some snacks will be provided before and after the talk.
