Location: MSRI: Online/Virtual
I am going to talk about birational automorphisms and situations when they are not regularizable. I will recall several known criteria for the non-existence of a regularization. I will give an example of a birational automorphism of a threefold when all these criteria do not work. Then introduce a new criterion which implies that the example is non-regularizable for some parameters.
