Atomic decompositions for derived categories of G-surfaces

Alexey Elagin, Julia Schneider, Evgeny Shinder

We construct canonical semi-orthogonal decompositions for derived categories of smooth projective surfaces. These decompositions are compatible with the operations in the minimal m…

Relations in the Cremona group over perfect fields

Julia Schneider

For perfect fields $k$ satisfying $[k ˉ : k] > 2$ , we construct new normal subgroups of the plane Cremona group and provide an elementary proof of its non-simplicity, following the…

Plane curves of fixed bidegree and their $A_{k}$ -singularities

Julia Schneider

We provide a tool how one can view a polynomial on the affine plane of bidegree $(a, b)$ - by which we mean that its Newton polygon lies in the triangle spanned by $(a, 0)$ , $(0, b)$ …
