Research activity

I am a fourth year Ph.D student in Algebraic Geometry, under the supervision of Prof. Ivan Cheltsov.

My research interests lie essentially in birational geometry, which includes rationality problems, minimal model program, and K-stability of Fano varieties. I am investigating these problems principally in a G-equivariant setting, and my current main focus is the finite subgroups of Cremona groups.

Publications and preprints

G-solid rational surfaces

We classify all the G-solid rational surfaces over the field of complex numbers, for finite group actions.

Published in European Journal of Mathematics.

Image

K-stability and space sextic curves of genus three

We study Fano threefolds obtained by blowing-up the three-dimensional projective space along a smooth curve of degree six and genus three.

Image

Finite linearizable subgroups of the plane Cremona group.

We give a complete solution to the linearization problem for finite groups in the plane Cremona group over an algebraically closed field of characteristic zero.

To appear soon.

ICMS conference on birational geometry and number theory, from 28/10/2024 to 01/11/2024.

Organised by Ivan Cheltsov, Daniel Loughran and myself.

Classifying varieties up to birational equivalence is one of the driving forces for modern research in algebraic geometry. Some of the greatest results in 20th and 21st Century algebraic geometry lie in birational geometry, with both Mori and Birkar awarded the Fields medal for their work in this area. Birational geometry has seen some very healthy and surprising interactions with number theory over the last decade.
