Derived Knörrer periodicity and Orlov's theorem for gauged Landau–Ginzburg models

Y Hirano - Compositio Mathematica, 2017 - cambridge.org
We prove a Knörrer-periodicity-type equivalence between derived factorization categories of
gauged Landau–Ginzburg models, which is an analogy of a theorem proved by Shipman …

Semiorthogonal decompositions and birational geometry of del Pezzo surfaces over arbitrary fields

A Auel, M Bernardara - Proceedings of the London …, 2018 - Wiley Online Library
We study the birational properties of geometrically rational surfaces from a derived
categorical perspective. In particular, we give a criterion for the rationality of a del Pezzo …

Semiorthogonal decompositions in families

A Kuznetsov - arXiv preprint arXiv:2111.00527, 2021 - arxiv.org
We discuss recent developments in the study of semiorthogonal decompositions of
algebraic varieties with an emphasis on their behaviour in families. First, we overview new …

A GLSM view on homological projective duality

Z Chen, J Guo, M Romo - Communications in Mathematical Physics, 2022 - Springer
Given a gauged linear sigma model (GLSM) TX realizing a projective variety X in one of its
phases, ie its quantum Kähler moduli has a geometric point, we propose an extended GLSM …

Hybrid models for homological projective duals and noncommutative resolutions

J Guo, M Romo - Letters in Mathematical Physics, 2022 - Springer
We study hybrid models arising as homological projective duals (HPD) of certain projective
embeddings f: X→ P (V) of Fano manifolds X. More precisely, the category of B-branes of …

Categorical Plücker formula and homological projective duality

Q Jiang, NC Leung, Y Xie - Journal of the European Mathematical …, 2021 - ems.press
Kuznetsov's homological projective duality (HPD) theory [K4] is one of the most active and
powerful recent developments in the homological study of algebraic geometry. The …

Cycles, derived categories, and rationality

A Auel, M Bernardara - Surveys on recent developments in …, 2017 - books.google.com
Our main goal is to give a sense of recent developments in the (stable) rationality problem
from the point of view of unramified cohomology and 0-cycles as well as derived categories …

Derived factorization categories of non‐Thom–Sebastiani‐type sums of potentials

Y Hirano, G Ouchi - Proceedings of the London Mathematical …, 2023 - Wiley Online Library
We first prove semi‐orthogonal decompositions of derived factorization categories arising
from sums of potentials of gauged Landau–Ginzburg models, where the sums are not …

[HTML][HTML] All complete intersection varieties are Fano visitors

YH Kiem, IK Kim, H Lee, KS Lee - Advances in Mathematics, 2017 - Elsevier
We prove that the derived category of a smooth complete intersection variety is equivalent to
a full subcategory of the derived category of a smooth projective Fano variety. This enables …

The homological projective dual of

JV Rennemo - Compositio Mathematica, 2020 - cambridge.org
We study the derived category of a complete intersection into a derived category of
factorisations on a Landau–Ginzburg (LG) model, and then apply VGIT to obtain a birational …
