Fukaya categories of Coulomb branches as unique deformations
Jasper van de Kreeke
The symplectic geometry of Coulomb branches is complicated and it is particularly difficult to determine their Fukaya categories. Relative Fukaya categories present an approach to…
A Hybrid Framework for Healing Semigroups with Machine Learning
Sarayu Sirikonda, Jasper van de Kreeke
In this paper, we propose a hybrid framework that heals corrupted finite semigroups, combining deterministic repair strategies with Machine Learning using a Random Forest Classifie…
The NilHecke schober
Jasper van de Kreeke
Perverse schobers can be used to describe Fukaya categories but are hard to axiomatize and construct. In this paper, we give an explicit construction of a perverse schober intended…
-spectral sequences for Hochschild cohomology
Jasper van de Kreeke
Spectral sequences are a common tool to compute cohomology spaces, but higher structure is often lost on the way. In this article we exhibit a strategy to retain the higher structu…
Resolution of singularities via Tannaka duality
Jasper van de Kreeke
Resolving finite quotient singularities is a classical problem in algebraic geometry. Traditional methods of Geometric Invariant Theory (GIT) translate the singularity into a quive…
Calabi-Yau techniques for Namikawa-Weyl groups
Jasper van de Kreeke
The field of symplectic singularities aims to build a 21st century Lie theory. A key development is the Namikawa-Weyl group, which generalizes the classical Weyl group of Lie algeb…
