The Jordan lattice completion and a note on injective envelopes and von Neumann algebras
, 2018 The article associates two fundamental lattice constructions with each regular unital real ordered Banach space (function system). These are used to establish certain results in the theory of operator algebras, specifically relating the injective ...

The Journal of Physiology, EarlyView.Abstract figure legend In this study, we used mathematical modelling to explore the effect of diabetes on muscle mechanoenergetics. Our parameterisation of cross‐bridge models using data from non‐diabetic and diabetic human atrial tissues revealed lower values for cross‐bridge stiffness, detachment rates, attachment rates and lower ATP sensitivity in ...

Testing Hypotheses of Covariate Effects on Topics of Discourse
Statistical Analysis and Data Mining: An ASA Data Science Journal, Volume 19, Issue 2, April 2026.ABSTRACT We introduce an approach to topic modeling with document‐level covariates that remains tractable in the face of large text corpora. This is achieved by de‐emphasizing the role of parameter estimation in an underlying probabilistic model, assuming instead that the data come from a fixed but unknown distribution whose statistical functionals are

Macroscopic Market Making Games
Mathematical Finance, Volume 36, Issue 2, Page 352-373, April 2026.ABSTRACT Building on the macroscopic market making framework as a control problem, this paper investigates its extension to stochastic games. In the context of price competition, each agent is benchmarked against the best quote offered by the others. We begin with the linear case.

Mathematika, Volume 72, Issue 2, April 2026.Abstract In this paper, we study traces of Hecke operators on Drinfeld modular forms of level 1 in the case A=Fq[T]$A = \mathbb {F}_q[T]$. We deduce closed‐form expressions for traces of Hecke operators corresponding to primes of degree at most 2 and provide algorithms for primes of higher degree.

Current state and prospects of research in thermoelasticity
Современная математика: Фундаментальные направленияA review of recent works on thermoelasticity is provided. It is recommended to use the boundary state method (BSM) for constructing numerical-analytical solutions of problems by means of computing systems supporting “computer algebras”. The structures of

Separable algebras over Prufer domains
Rocky Mountain Journal of Mathematics, 1975 Employing sheaf-theoretic techniques and idempotent lifting properties, the following extension of the Wedderburn Principal Theorem is shown: If A is any finitely generated algebra over an almost Dedekind domain R such that A modulo its Baer lower radical is separable over R, then A contains a separable subalgebra S which adds with the lower radical as

C∞‐Structures for Liénard Equations and New Exact Solutions to a Class of Klein–Gordon Equations
Mathematical Methods in the Applied Sciences, Volume 49, Issue 4, Page 2795-2822, 15 March 2026.ABSTRACT Liénard equations are analyzed using the recent theory of 𝒞∞‐structures. For each Liénard equation, a 𝒞∞‐structure is determined by using a Lie point symmetry and a 𝒞∞‐symmetry. Based on this approach, a novel method for integrating these equations is proposed, which consists in solving sequentially two completely integrable Pfaffian equations.

On simplicity of Cuntz algebras and its applications [PDF]
Surveys in Mathematics and its ApplicationsCuntz algebra 𝒪2 is the universal C*-algebra generated by two isometries s1, s2 satisfying s1s1*+s2s2*=1. This is separable, simple, infinite C*-algebra containing a copy of any nuclear C*-algebra.

Polarization Formulas over Separable Algebras
Journal of Algebra, 1995 Let \(J\) be an involution on a ring \(A\). Motivated by the question of representing hermitian forms, the author defines a polarization on \(A\) to be an identity \(x=\sum_ik_i[l_ixm_i+(l_ixm_i)^J]n_i\), where \(k_i\), \(l_i\), \(m_i\), \(n_i\) are constants in \(A\).
