Global well‐posedness and large‐time behavior for non‐isothermal nematic liquid crystal flows with temperature‐dependent viscosity

open access: yesTransactions of the London Mathematical Society, Volume 13, Issue 1, December 2026.
Abstract We investigate an initial‐boundary value problem of non‐isothermal nematic liquid crystal flows with temperature‐dependent viscosity in three‐dimensional bounded domains. Based on the time‐weighted energy estimates, we derive the existence of a unique global strong solution under some smallness condition.

New Thermal Lattice Boltzmann Method for Modeling Heat Transfer Problems Considering Temperature‐Dependent Properties

open access: yesHeat Transfer, Volume 55, Issue 7, Page 4554-4567, November 2026.
ABSTRACT Several engineering problems involve the need to model conjugate heat transfer processes considering the temperature‐dependence of the material properties. Consequently, a simulation tool capable of modeling this process is of great interest. In this context, the present work proposes a thermal lattice Boltzmann method (TLBM) for modeling the ...

The Haagerup property is not invariant under quasi‐isometry

open access: yesBulletin of the London Mathematical Society, Volume 58, Issue 11, November 2026.
Abstract Using the work of Cornulier–Valette and Whyte (see Appendix A for the latter), we show that neither the Haagerup property nor weak amenability is invariant under quasi‐isometry of finitely generated groups. Appendix B shows, using the same examples, that the same holds for vanishing of the equivariant Lp$L^p$‐compression.

A Unified Block‐Modal Framework for Inverse Source Problems in Heat and Mass Transfer

open access: yesInternational Journal for Numerical Methods in Engineering, Volume 127, Issue 19, 15 October 2026.
ABSTRACT This work presents a unified block–modal framework for inverse source identification in linear diffusive problems arising in heat and mass transfer. Starting from a general parabolic model with mixed boundary operators, the Classical Integral Transform Technique is employed to project the dynamics onto an orthonormal eigenbasis, yielding a ...

Characterization theorems in von Neumann algebras [PDF]

open access: yes, 1990
Dissertation (MSc)--University of Pretoria, 1990.The aim of this thesis is to study the characterization theorems in von Neumann algebras. This class of operator algebras was defined for the first time in 1930 by J von Neumann in terms of a ...

Popa's intertwining theory for type III factors

open access: yes, 2020
Popa's intertwining theory is a very powerful tool to study inclusions of finite von Neumann algebras. This is in fact one of the most important technical ingredient in Popa's deformation/rigidity theory.

Nonlinear Mixed Bi-Skew Jordan-Type Higher Derivations on ∗-Algebras

open access: yesMathematics
Let A be a unital ∗-algebra containing a nontrivial projection. In this paper, we show that every nonlinear mixed bi-skew Jordan-type higher derivation on A is an additive higher ∗-derivation.

Von Neumann algebras in double-scaled SYK

open access: yesJournal of High Energy Physics
It has been argued that a finite effective temperature emerges and characterizes the thermal property of double-scaled SYK model in the infinite temperature limit [1]. Meanwhile, in the static patch of de Sitter, the maximally entangled state satisfies a
