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 ...

On Frobenius algebras

open access: yesJournal of Algebra, 2003
The paper under review studies Frobenius factor algebras of finite dimensional algebras. Let \(D(\Lambda)\) be the \(K\)-dual of a finite dimensional \(K\)-algebra \(\Lambda\). Then \(D(\Lambda)\) becomes naturally a left and right \(\Lambda\)-module.

Subring Depth, Frobenius Extensions, and Towers

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2012
The minimum depth d(B,A) of a subring B⊆A introduced in the work of Boltje, Danz and Külshammer (2011) is studied and compared with the tower depth of a Frobenius extension.

Approximating Hamiltonian dynamics with the Nyström method [PDF]

open access: yesQuantum, 2020
Simulating the time-evolution of quantum mechanical systems is BQP-hard and expected to be one of the foremost applications of quantum computers. We consider classical algorithms for the approximation of Hamiltonian dynamics using subsampling methods ...

Edge contraction on dual ribbon graphs and 2D TQFT

open access: yes, 2017
We present a new set of axioms for 2D TQFT formulated on the category of cell graphs with edge-contraction operations as morphisms. We construct a functor from this category to the endofunctor category consisting of Frobenius algebras.

Hilbertian Frobenius algebras [PDF]

open access: yesCommunications in Algebra, 2021
Commutative Hilbertian Frobenius algebras are those commutative semi-group objects in the monoidal category of Hilbert spaces, for which the Hilbert adjoint of the multiplication satisfies the Frobenius compatibility relation, that is, this adjoint is a bimodule map. In this note we prove that they split as an orthogonal direct sum of two closed ideals,

Extensions of pseudo-Perron-Frobenius splitting related to generalized inverse AT,S(2)

open access: yesSpecial Matrices, 2018
We in this paper define the outer-Perron-Frobenius splitting, which is an extension of the pseudo- Perron-Frobenius splitting defined in [A.N. Sushama, K. Premakumari, K.C.

KdV hierarchies and quantum Novikov's equations [PDF]

open access: yesOpen Communications in Nonlinear Mathematical Physics
This paper begins with a review of the well-known KdV hierarchy, the $N$-th Novikov equation, and its finite hierarchy in the classical commutative case. This finite hierarchy consists of $N$ compatible integrable polynomial dynamical systems in $\mathbb{

On properties of principal elements of Frobenius Lie algebras [PDF]

open access: yes, 2014
We investigate the properties of principal elements of Frobenius Lie algebras, following the work of M. Gerstenhaber and A. Giaquinto. We prove that any Lie algebra with a left symmetric algebra structure can be embedded, in a natural way, as a ...

Self‐Similar Blowup for the Cubic Schrödinger Equation

open access: yesCommunications on Pure and Applied Mathematics, EarlyView.
ABSTRACT We give a rigorous proof for the existence of a finite‐energy, self‐similar solution to the focusing cubic Schrödinger equation in three spatial dimensions. The proof is computer‐assisted and relies on a fixed point argument that shows the existence of a solution in the vicinity of a numerically constructed approximation.
