Equivariant birational geometry of linear actions
Yuri Tschinkel, Kaiqi Yang, Zhijia Zhang
We study linear actions of finite groups in small dimensions, up to equivariant birationality.
Combinatorial Burnside groups
Yuri Tschinkel, Kaiqi Yang, Zhijia Zhang
We study the structure of combinatorial Burnside groups, which receive equivariant birational invariants of actions of finite groups on algebraic varieties.
Potentially stably rational del Pezzo surfaces over nonclosed fields
Yuri Tschinkel, Kaiqi Yang
We classify Galois actions on Picard lattices of del Pezzo surfaces of degrees 1,2, and 3 giving rise to minimal surfaces with no cohomological obstructions to stable rationality.
Spatial nonhomogeneous periodic solutions induced by nonlocal prey competition in a diffusive predator-prey model
Shanshan Chen, Junjie Wei, Kaiqi Yang
The diffusive Holling-Tanner predator-prey model with no-flux boundary conditions and nonlocal prey competition is considered in this paper. We show the existence of spatial nonhom…
