The Rank-One property for free Frobenius extensions

open access: yesComptes Rendus. Mathématique, 2023
A conjecture by the second author, proven by Bonnafé–Rouquier, says that the multiplicity matrix for baby Verma modules over the restricted rational Cherednik algebra has rank one over $\mathbb{Q}$ when restricted to each block of the algebra.In this ...

Cartan invariant matrices for finite monoids [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2012
Let $M$ be a finite monoid. In this paper we describe how the Cartan invariant matrix of the monoid algebra of $M$ over a field $\mathbb{K}$ of characteristic zero can be expressed using characters and some simple combinatorial statistic.

Cluster Structures on Double Bott–Samelson Cells

open access: yesForum of Mathematics, Sigma, 2021
Let $\mathsf {C}$ be a symmetrisable generalised Cartan matrix. We introduce four different versions of double Bott–Samelson cells for every pair of positive braids in the generalised braid group associated to $\mathsf {C}$ .

On the Higher Nash Blow-Up Derivation Lie Algebras of Isolated Hypersurface Singularities

open access: yesMathematics, 2023
It is a natural question to ask whether there is any Lie algebra that completely characterize simple singularities? The higher Nash blow-up derivation Lie algebras Lkl(V) associated to isolated hypersurface singularities defined to be the Lie algebra of ...

Lax pairs for string Newton Cartan geometry

open access: yesNuclear Physics B, 2020
In this paper, based on a systematic formulation of Lax pairs, we show classical integrability for nonrelativistic strings propagating over stringy Newton-Cartan (NC) geometry.

Semiclassical dynamics for torsional Newton-Cartan strings

open access: yesNuclear Physics B, 2020
We explore folded spinning string configurations over torsional Newton Cartan (TNC) geometry with R×S2 topology within the semiclassical approximation. We consider the large c and/or nonrelativistic (NR) limit associated with the world-sheet d.o.f.

A new class of higher quantum Airy structures as modules of $\mathcal{W}(\mathfrak{gl}_r)$-algebras

open access: yesSciPost Physics, 2023
Quantum $r$-Airy structures can be constructed as modules of $\mathcal{W}(\mathfrak{gl}_r)$-algebras via restriction of twisted modules for the underlying Heisenberg algebra.

Aspects of Nonrelativistic Strings

open access: yesFrontiers in Physics, 2022
We review recent developments on nonrelativistic string theory. In flat spacetime, the theory is defined by a two-dimensional relativistic quantum field theory with nonrelativistic global symmetries acting on the worldsheet fields.

Polyadic Braid Operators and Higher Braiding Gates

open access: yesUniverse, 2021
A new kind of quantum gates, higher braiding gates, as matrix solutions of the polyadic braid equations (different from the generalized Yang–Baxter equations) is introduced. Such gates lead to another special multiqubit entanglement that can speed up key

T-duality in nonrelativistic open string theory

open access: yesJournal of High Energy Physics, 2021
Nonrelativistic open string theory is defined by a worldsheet theory that produces a Galilean invariant string spectrum and is described at low energies by a nonrelativistic Yang-Mills theory [1].
