Derived algebraic geometry [PDF]

open access: yesEMS Surveys in Mathematical Sciences, 2014
This text is a survey of derived algebraic geometry. It covers a variety of general notions and results from the subject with a view on the recent developments at the interface with deformation quantization.

Interpretability and Representability of Commutative Algebra, Algebraic Topology, and Topological Spectral Theory for Real-World Data. [PDF]

open access: yesAdv Intell Discov
This article investigates how persistent homology, persistent Laplacians, and persistent commutative algebra reveal complementary geometric, topological, and algebraic invariants or signatures of real‐world data. By analyzing shapes, synthetic complexes, fullerenes, and biomolecules, the article shows how these mathematical frameworks enhance ...

Formalization and Implementation of Algebraic Methods in Geometry [PDF]

open access: yesElectronic Proceedings in Theoretical Computer Science, 2012
We describe our ongoing project of formalization of algebraic methods for geometry theorem proving (Wu's method and the Groebner bases method), their implementation and integration in educational tools.

Families of stable 3-folds in positive characteristic [PDF]

open access: yesÉpijournal de Géométrie Algébrique, 2023
We show that flat families of stable 3-folds do not lead to proper moduli spaces in any characteristic $p>0$. As a byproduct, we obtain log canonical 4-fold pairs, whose log canonical centers are not weakly normal.

How to glue derived categories

open access: yesBulletin of Mathematical Sciences, 2018
We give an overview of existing enhancement techniques for derived and trianguated categories based on the notion of a stable model category, and show how it can be applied to the problem of gluing triangulated categories.

Hilbert-Mumford stability on algebraic stacks and applications to $\mathcal{G}$-bundles on curves [PDF]

open access: yesÉpijournal de Géométrie Algébrique, 2018
In these notes we reformulate the classical Hilbert-Mumford criterion for GIT stability in terms of algebraic stacks, this was independently done by Halpern-Leinster.

Exceptional collections on certain Hassett spaces [PDF]

open access: yesÉpijournal de Géométrie Algébrique, 2021
We construct an $S_2\times S_n$ invariant full exceptional collection on Hassett spaces of weighted stable rational curves with $n+2$ markings and weights $(\frac{1}{2}+\eta, \frac{1}{2}+\eta,\epsilon,\ldots,\epsilon)$, for ...

Algebraic Geometry over Heyting Algebras [PDF]

open access: yesJournal of Siberian Federal University. Mathematics & Physics, 2020
In this article, we study the algebraic geometry over Heyting algebras and we investigate the properties of being equationally Noetherian and qω-compact over such ...

Stable rationality of higher dimensional conic bundles [PDF]

open access: yesÉpijournal de Géométrie Algébrique, 2018
We prove that a very general nonsingular conic bundle $X\rightarrow\mathbb{P}^{n-1}$ embedded in a projective vector bundle of rank $3$ over $\mathbb{P}^{n-1}$ is not stably rational if the anti-canonical divisor of $X$ is not ample and $n\geq 3$.
