On $p$-convexification of the Banach-Kantorovich lattice [PDF]
E-Journal of Analysis and Applied MathematicsLet $B$ be a complete Boolean algebra, $Q(B)$ the Stone compact of $B$, and let $C_\infty (Q(B))$ be the commutative unital algebra of all continuous functions $x: Q(B) \to [-\infty, +\infty]$, assuming possibly the values $\pm\infty$ on nowhere-dense ...

Equidistribution in 2‐nilpotent Polish groups and triple restricted sumsets
Journal of the London Mathematical Society, Volume 114, Issue 3, September 2026.Abstract The aim of this paper is to establish a Ratner‐type equidistribution theorem for orbits on homogeneous spaces associated with 2$\hskip.001pt 2$‐nilpotent locally compact Polish groups under the action of a countable discrete abelian group.

A new approach for the analysis of evolution partial differential equations on a finite interval
Journal of the London Mathematical Society, Volume 114, Issue 3, September 2026.Abstract We show that, for certain evolution partial differential equations, the solution on a finite interval (0,ℓ)$(0,\ell)$ can be reconstructed as a superposition of restrictions to (0,ℓ)$(0,\ell)$ of solutions to two associated partial differential equations posed on the half‐lines (0,∞)$(0,\infty)$ and (−∞,ℓ)$(-\infty,\ell)$.

On the ideals of extended quasi-nilpotent Banach algebras
International Journal of Mathematics and Mathematical Sciences, 1991 Given a quasi-nilpotent Banach algebra A, we will use the results of Seddighin [2], to study the properties of elements which belong to a proper closed two sided ideal of A¯ and A¯¯. Here A¯ is the extension of A to a Banach Algebra with identity.

Self‐Similar Blowup for the Cubic Schrödinger Equation
Communications on Pure and Applied Mathematics, Volume 79, Issue 8, Page 1831-1918, August 2026.ABSTRACT We give a rigorous proof for the existence of a finite‐energy, self‐similar solution to the focusing cubic Schrödinger equation in three spatial dimensions. The proof is computer‐assisted and relies on a fixed point argument that shows the existence of a solution in the vicinity of a numerically constructed approximation.

Fixed point characterization of left amenable Lau algebras
International Journal of Mathematics and Mathematical Sciences, 2004 The present paper deals with the concept of left amenability for a wide range of Banach algebras known as Lau algebras. It gives a fixed point property characterizing left amenable Lau algebras 𝒜 in terms of left Banach 𝒜-modules.

ON DERIVATIONS IN BANACH ALGEBRAS
Bulletin of the Korean Mathematical Society, 2002 The authors prove that: (i) The only Jordan derivations \(D\) and \(G\) on a non-commutative \((n+1)!\) torsion free prime ring \(R\) such that \(D(x)x^n-x^nG(x)\) is in the center of \(R\) for all \(x\in R\) are \(D=0\) and \(G=0\); (ii) The only derivation \(D\) on a non-commutative 2-torsion free prime ring \(R\) such that the mapping \(x\rightarrow

Nice connecting paths in connected components of sets of algebraic elements in a Banach algebra [PDF]
, 2016 Generalizing earlier results about the set of idempotents in a Banach algebra, or of self-adjoint idempotents in a C*-algebra, we announce constructions of nice connecting paths in the connected components of the set of elements in a Banach algebra, or ...
