Discrete q-Hermitian Clifford analysis

Baruch Schneider, Diana Schneiderová, Yifan Zhang

We develop a discrete -Hermitian Clifford calculus based on coordinatewise Jackson differences on multiplicative -lattices. The resulting Hermitian Jackson--Dirac operators a…

Optimal location of small favourable regions for Robin eigenvalues with indefinite weights

Baruch Schneider, Diana Schneiderová, Yifan Zhang

We consider the positive principal eigenvalue of an elliptic problem with a Robin boundary condition and bang--bang indefinite weight , and a…

A Chain- and Diagram-Level Semantics for Morphological Calculus Refinement, monodromy, and bivector orbit decompositions

Baruch Schneider, Diana Schneiderová, Yifan Zhang

Morphological calculus represents decompositions of geometric objects by polynomial-like expressions in a symbol for the real line, but scalar operations suppress the incidence and…

Stable -Hermitian coordinate calculus: Capelli--PBW transport, mixed polarization algebra, and localization obstructions

Baruch Schneider, Diana Schneiderová, Yifan Zhang

We extend a finite-support -Hermitian radial calculus to Clifford-valued coordinate polynomials. For bosonic Hermitian vector labels and finite fermionic support, the stable…

Lieb-Thirring bounds for Melik-Adamyan canonical Hamiltonians

Baruch Schneider, Diana Barseghyan Schneiderová, Yifan Zhang

We study a class of positive matrix Hamiltonians arising from the canonical differential expressions of Melik--Adamyan and appearing in the appendix of Alpay--Gohberg. Let and…

Asymptotic minimization of the first Dirichlet eigenvalue in a square with two hard obstacles

Baruch Schneider, Diana Schneiderová, Yifan Zhang

We study an asymptotic minimization problem for the first Dirichlet eigenvalue in the square , where two equal hard circular obstacles of radius move inside wit…

One-dimensional optimisation of indefinite-weight principal eigenvalues with asymmetric Robin parameters and a Schrödinger-type perturbation

Baruch Schneider, Diana Schneiderová, Yifan Zhang

We study the minimisation of the positive principal eigenvalue for an indefinite-weight problem with asymmetric Robin parameters. The model is motivated by diffusive logistic equat…

Optimisation of Robin Laplacian eigenvalue with indefinite weight in spherical shell

Baruch Schneider, Diana Schneiderova, Yifan Zhang

This paper is concerned with an optimisation problem of Robin Laplacian eigenvalue with respect to an indefinite weight, which is formulated as a shape optimisation problem thanks…
