Title: Intersection number formula on Lubin-Tate spaces (Note special day and room)
Abstract: We consider a moduli space classifying deformations of a formal module over the algebraic closure of the finite field F_q. Those spaces are called Lubin Tate deformation spaces. We will construct some CM cycles on this space. By adding Drinfeld level structures, we proved a formula for the intersection number between these CM cycles. As an application, this formula gives a new proof of Keating's results on endomorphism lifting problems for formal modules over the algebraic closure of F_q.
