Dr. Robert Smiech, University of Edinburgh: G-birational rigidity of del Pezzo threefolds of degree 4
For a Fano variety equipped with an action of a (finite) group G, one can consider a G-equivariant Mori Program along with related notions, like G-solidity or G-birational rigidity. One of the most interesting questions that can be posed in such a setting is as follows: if H is a subgroup of G and X is a H-birationally rigid H-Fano, is X G-birationally rigid? In my talk I will present the results of my research into this question for del Pezzo threefolds of degree 4.

Dr. Enrique Becerra, CINVESTAV: The Stringy Spectrum of Projective Varieties: A Dual Perspective
We introduce the "stringy spectrum," a new invariant for projectivevarieties defined via the monodromic motivic volume of the projective dual. After examining how dual singularities encode spectral properties through motivic integration, we derive a blow-up formula for this invariant and discuss its behavior under birational transformations. Finally, we explore how the arithmetic of the spectrum’s exponents provides potential obstructions to rationality.
