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. Sommen's examples reveal two basic difficulties:…

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…

Exceptional supersphere integration and logarithmic Pizzetti kernels

Juan Bory-Reyes, Baruch Schneider, Diana Schneiderova +1

We study orthosymplectically invariant supersphere integration at the exceptional superdimensions , where the harmonic Fischer structure becomes nonsemisimple and the Pizzet…

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 $…

Right q-vector calculus at integral superdimension: localized decompositions and resonance

Juan Bory-Reyes, Baruch Schneider, Diana Barseghyan Schneiderová +1

We specialize the intrinsic right -vector derivative on radial algebras to integral superdimension. The formal dimension is encoded by an independent coefficient , and formal…

Global small-hole minimization of the first Dirichlet eigenvalue in a square with two hard obstacles

Baruch Schneider, Diana Schneiderová, Yifan Zhang

We study the global minimization of the first Dirichlet eigenvalue of a square containing two equal non-overlapping circular obstacles as their common radius tends to zero. A c…
