Valuation Semigroups of Two Dimensional Local Rings

open access: yes, 2014
We consider the question of when a semigroup is the semigroup of a valuation dominating a two dimensional noetherian local domain, giving some surprising examples.

Hausdorff dimensions of irreducible Markov hom tree‐shifts

open access: yesJournal of the London Mathematical Society, Volume 111, Issue 6, June 2025.
Abstract This paper features a Cramér's theorem for finite‐state Markov chains indexed by rooted d$d$‐trees, obtained via the method of types in the classical analysis of large deviations. Along with the theorem comes two applications: an almost‐sure type convergence of sample means and a formula for the Hausdorff dimension of the symbolic space ...

Quotient semigroups and extension semigroups

open access: yesProceedings - Mathematical Sciences, 2012
We discuss properties of quotient semigroup of abelian semigroup from the viewpoint of C*-algebra and apply them to a survey of extension semigroups. Certain interrelations among some equivalence relations of extensions are also considered.

Analyticity of the Stokes semigroup in spaces of bounded functions

open access: yes, 2011
The analyticity of the Stokes semigroup with the Dirichlet boundary condition is established in spaces of bounded functions when the domain occupied with fluid is bounded or more generally admissible which admits a special estimate for the Helmholtz ...

Traces on the uniform tracial completion of Z$\mathcal {Z}$‐stable C∗${\rm C}^*$‐algebras

open access: yesJournal of the London Mathematical Society, Volume 111, Issue 6, June 2025.
Abstract The uniform tracial completion of a C∗${\rm C}^*$‐algebra A$A$ with compact trace space T(A)≠∅$T(A) \ne \emptyset$ is obtained by completing the unit ball with respect to the uniform 2‐seminorm ∥a∥2,T(A)=supτ∈T(A)τ(a∗a)1/2$\Vert a\Vert _{2,T(A)}=\sup _{\tau \in T(A)} \tau (a^*a)^{1/2}$. The trace problem asks whether every trace on the uniform

On a semitopological polycyclic monoid [PDF]

open access: yes, 2016
We study algebraic structure of the $\lambda$-polycyclic monoid $P_{\lambda}$ and its topologizations. We show that the $\lambda$-polycyclic monoid for an infinite cardinal $\lambda\geqslant 2$ has similar algebraic properties so has the polycyclic ...

General Decay and Blowing‐Up Solutions of a Nonlinear Wave Equation With Nonlocal in Time Damping and Infinite Memory

open access: yesMathematical Methods in the Applied Sciences, Volume 48, Issue 8, Page 9046-9057, 30 May 2025.
ABSTRACT This paper shows that long‐term stability and blowing‐up solutions for a nonlinear wave equation with a nonlocal damping of Choi and MacCamy type and a nonlocal dispersion can occur. The method of proof of general decay relies on a suitable Lyapunov functional.

Γ – semigroup generated by a semigroup

open access: yesJournal of Physics: Conference Series, 2020
Abstract In Γ – semigroup S, the element of Γ maybe a binary operation in S. Every element of any semigroupS can define a binary operation in S. A collection of binary operations defined of the element of S generates Γ – semigroup S.

A Strong Approximation in L2 for the Solutions of the Maxwell System With Highly Oscillating Periodic Coefficients

open access: yesMathematical Methods in the Applied Sciences, Volume 48, Issue 8, Page 9207-9224, 30 May 2025.
ABSTRACT We consider a Maxwell system on ℝ3$$ {\mathbb{R}}^3 $$ with highly oscillating periodic coefficients. It is known that the solutions converge in the weak‐ ∗$$ \ast $$ topology of L∞(0,T;L2(ℝ3))$$ {L}^{\infty}\left(0,T;\kern0.3em {L}^2\left({\mathbb{R}}^3\right)\right) $$ to the solution of a similar problem with constant coefficients given as ...
