A general approach to the linear stability of viscoelastic shear‐flows
ZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, Volume 106, Issue 2, February 2026.Abstract The present work provides an in‐depth analysis of the linear stability theory of viscoelastic shear‐flows, based upon a constitutive equation of the fading memory type. The particular model considered herein was introduced by Kenneth Walters through the integration of classical rate‐type fluids in a convected frame (Walters 1962).

Barbasch-Sahi algebras and Dirac cohomology [PDF]
Transactions of the American Mathematical Society, 2019 We define a class of algebras which are distinguished by a PBW property and an orthogonality condition, and which we call Hopf-Hecke algebras, since they generalize the Drinfeld Hecke algebras defined by Drinfeld. In the course of studying the orthogonality condition and in analogy to the orthogonal group we show the existence of a pin cover for ...

Stochastic Resonance Elucidates the Emergence and Periodicity Transition of Glacial Cycles
Geophysical Research Letters, Volume 53, Issue 1, 16 January 2026.Abstract Glacial cycles emerged with a 41‐kyr period after the Pliocene and later intensified with a 100‐kyr period in the mid‐Pleistocene, which were attributed to Earth's orbital variations. However, no significant changes in the orbital forcing were found at the two transitions, and the forcing was too small to drive these cycles. Here, a stochastic

Dirac cohomology for symplectic reflection algebras [PDF]
Selecta Mathematica, 2015 We define uniformly the notions of Dirac operators and Dirac cohomology in the framework of the Hecke algebras introduced by Drinfeld. We generalize in this way the Dirac cohomology theory for Lusztig's graded affine Hecke algebras. We apply these constructions to the case of symplectic reflection algebras defined by Etingof-Ginzburg, particularly to ...

Abstract Boundary Delay Systems and Application to Network Flow
Mathematical Methods in the Applied Sciences, Volume 49, Issue 1, Page 119-129, 15 January 2026.ABSTRACT This paper investigates the well‐posedness and positivity of solutions to a class of delayed transport equations on a network. The material flow is delayed at the vertices and along the edges. The problem is reformulated as an abstract boundary delay equation, and well‐posedness is proved by using the Staffans–Weiss theory.

Manifestly Conformal Descriptions and Higher Symmetries of Bosonic Singletons
Symmetry, Integrability and Geometry: Methods and Applications, 2010 The usual ambient space approach to conformal fields is based on identifying the d-dimensional conformal space as the Dirac projective hypercone in a flat d+2-dimensional ambient space. In this work, we explicitly concentrate on singletons of any integer

Von Neumann Algebra Invariants of Dirac Operators
Journal of Functional Analysis, 1998 A Novikov-Shubin invariant associated to the Dirac operator on \(L^2\)-spinors on the universal covering space of a compact Riemannian spin manifold is studied. This is a conformal invariant but it does depend on the conformal class. If this invariant is positive one can define the von Neumann algebra determinant of the Dirac Laplacian.
