Maximal subsemigroups of the semigroup of all mappings on an infinite set [PDF]

open access: yes, 2013
In this paper we classify the maximal subsemigroups of the \emph{full transformation semigroup} $\Omega^\Omega$, which consists of all mappings on the infinite set $\Omega$, containing certain subgroups of the symmetric group $\sym(\Omega)$ on $\Omega ...

OMEGA PHOTOPRODUCTION [PDF]

open access: yesMeson 2002, 2003
Photoproduction of omega-meson is analyzed within meson exchange model and Regge model and compared to rho-meson photoproduction. An interplay between two models and uncertainties in data reproduction are discussed.

The geometrical quantity in damped wave equations on a square [PDF]

open access: yes, 2006
The energy in a square membrane $\Omega$ subject to constant viscous damping on a subset $\omega\subset \Omega$ decays exponentially in time as soon as $\omega$ satisfies a geometrical condition known as the "Bardos-Lebeau-Rauch" condition.

The two-phase problem for harmonic measure in VMO [PDF]

open access: yes, 2020
Let $\Omega^+\subset\mathbb R^{n+1}$ be an NTA domain and let $\Omega^-= \mathbb R^{n+1}\setminus \overline{\Omega^+}$ be an NTA domain as well. Denote by $\omega^+$ and $\omega^-$ their respective harmonic measures.

An example concerning Sadullaev's boundary relative extremal functions [PDF]

open access: yes, 2018
We exhibit a smoothly bounded domain $\Omega$ with the property that for suitable $K\subset\partial \Omega$ and $z\in \Omega$ the "Sadullaev boundary relative extremal functions" satisfy the inequality $\omega_1(z,K,\Omega)

On a P\'olya functional for rhombi, isosceles triangles, and thinning convex sets [PDF]

open access: yes, 2019
Let $\Omega$ be an open convex set in ${\mathbb R}^m$ with finite width, and let $v_{\Omega}$ be the torsion function for $\Omega$, i.e. the solution of $-\Delta v=1, v\in H_0^1(\Omega)$.

Global attractors for strongly damped wave equations with displacement dependent damping and nonlinear source term of critical exponent [PDF]

open access: yes, 2011
In this paper the long time behaviour of the solutions of 3-D strongly damped wave equation is studied. It is shown that the semigroup generated by this equation possesses a global attractor in H_{0}^{1}(\Omega)\times L_{2}(\Omega) and then it is proved ...

The Rank of Tree-Automatic Linear Orderings [PDF]

open access: yes, 2012
We generalise Delhomm\'e's result that each tree-automatic ordinal is strictly below \omega^\omega^\omega{} by showing that any tree-automatic linear ordering has FC-rank strictly below \omega^\omega.
