De Fernex and Hacon associated a multiplier ideal sheaf to a
pair $(X, \mathfrak a^c)$ consisting of a normal variety and a
closed subscheme, which generalizes the usual notion where the
canonical divisor $K_X$ is assumed to be Q-Cartier. I will...
The minimal log discrepancy is a measure of singularities of
pairs. While akin to the log canonical threshold, it turns out to
be much more difficult to study, with many questions still open. I
will discuss a question about the boundedness of...
We discuss developments in motivic homotopy theory over the last
ten years, including structural aspects, the role of Postnikov
towers, oriented theories and quadratic forms.
Let $X$ be a smooth canonically polarised surface defined over
an algebraically closed field of characteristic 2. In this talk I
will present some results about the geometry of $X$ in the case
when the automorphism scheme $\mathrm{Aut}(X)$ of $X$ is...
