Linearising groups
2 PM, 29 Apr 2025
Antoine Pinardin presents a complete description of the linearisable subgroups of the plane Cremona group over the field of complex numbers.
Mr Pinardin is a PhD student at the University of Edinburgh. He addresses the problem of describing the linearizable subgroups of the plane Cremona group, the group of birational self-maps of the projective plane. Drawing on work with Drs Arman Sarikyan and Egor Yasinsky, Mr Pinardin gives a complete solution to this problem, equivalent to the question of G-equivariant rationality, over the field of complex numbers.
