Analysis of a Viscoplastic Burgers Equation

Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 2, June 2026.
ABSTRACT We study a Burgers equation featuring an additional stress term that is governed by a positively 1$\hskip.001pt 1$‐homogeneous potential. This problem is motivated by the so‐called Hibler's sea ice model, which treats sea ice as a non‐Newtonian fluid, where the stress tensor includes such a term in order to account for the plastic response of ...

Compact well-bounded operators

, 2001
Every compact well-bounded operator has a representation as a linear combination of disjoint projections reminiscent of the representation of compact self-adjoint operators. In this note we show that the converse of this result holds, thus characterizing

Positive forms on Banach spaces

, 2003
The first representation theorem establishes a correspondence between positive, self-adjoint operators and closed, positive forms on Hilbert spaces.

Mimicking the Ocean: Critical Challenges in Scaffold Design and Tissue Texturization for Cell‐Cultured Seafood

Journal of Food Science, Volume 91, Issue 6, June 2026.
ABSTRACT Cellular aquaculture offers a sustainable solution to global seafood demand, yet the production of high‐value, whole‐cut fillets is hindered by the “texture gap,” the inability to replicate the complex, anisotropic architecture of native fish muscle and its collagenous myosepta.

Tensor products of abstract Besov spaces

Karpatsʹkì Matematičnì Publìkacìï, 2012
We prove the interpolation theorem for tensor products of abstract Besov spaces, associated with closed operators in Banach spaces and show its application to the problems of approximations of elements of tensor products of Banach spaces.

A Theorem of Rolewicz's Type for Measurable Evolution Families in Banach Spaces

, 2001
Let $varphi$ be a positive and non-decreasing function defined on the real half-line and ${mathcal U}$ be a strongly measurable, exponentially bounded evolution family of bounded linear operators acting on a Banach space and satisfing a certain ...

On an improved restricted reverse weak‐type bound for the maximal operator

Bulletin of the London Mathematical Society, Volume 58, Issue 6, June 2026.
Abstract We obtain an improved lower bound for the restricted reverse weak‐type estimate of the Hardy–Littlewood maximal operator M$M$. This result is applied to the λ$\lambda$‐median maximal operator mλ$m_{\lambda }$ acting on a Banach function space X$X$.

Type, cotype and convexity properties of quasi-Banach spaces [Elektronisk resurs]

, 2004
Results on quasi-Banach spaces, their type and cotype together with the convexity and concavity of quasi-Banach lattices are collected. Several proofs are included.

Isometries of the unitary groups and Thompson isometries of the spaces of invertible positive elements in C*-algebras

, 2014
We show that the existence of a surjective isometry (which is merely a distance preserving map) between the unitary groups of unital C*-algebras implies the existence of a Jordan *-isomorphism between the algebras.
