A categorical Torelli theorem for quartic del Pezzo surfaces

Alexey Elagin

We solve categorical Torelli problem for quartic del Pezzo surfaces. That is, we prove that a del Pezzo surface of degree can be canonically reconstructed from its Kuznetsov co…

On cyclic strong exceptional collections of line bundles on surfaces

Alexey Elagin, Junyan Xu, Shizhuo Zhang

We study exceptional collections of line bundles on surfaces. We prove that any full cyclic strong exceptional collection of line bundles on a rational surface is an augmentation i…

Calculating dimension of triangulated categories: path algebras, their tensor powers and orbifold projective lines

Alexey Elagin

This is a companion paper of arXiv:1901.09461, where different notions of dimension for triangulated categories are discussed. Here we compute dimensions for some examples of trian…

Derived categories of coherent sheaves on some zero-dimensional schemes

Alexey Elagin, Valery A. Lunts

Let be the second infinitesimal neighborhood of a closed point in -dimensional affine space. In this note we study , the bounded derived category of cohere…

Three notions of dimension for triangulated categories

Alexey Elagin, Valery A. Lunts

In this note we discuss three notions of dimension for triangulated categories: Rouquier dimension, diagonal dimension and Serre dimension. We prove some basic properties of these…
