"Contracting rays in NE(X) for horospherical X"

I will continue with section 3 of Brion’s paper “Variétés sphériques et théorie de Mori”. This time we will start to see how contracting extremal rays of NE(X) affects the coloured fan of X.

This seminar will be held jointly online and in person:

Jenny Xu, Department of Pure Mathematics, University of Waterloo

"An Invitation to Model-Theoretic Galois Theory (Part I)"

Robert Cornea, Department of Pure Mathematics, University of Waterloo
