Riesz transforms on solvable extensions of stratified groups [PDF]
, 2018 Let $G = N \rtimes A$, where $N$ is a stratified group and $A = \mathbb{R}$ acts on $N$ via automorphic dilations. Homogeneous sub-Laplacians on $N$ and $A$ can be lifted to left-invariant operators on $G$ and their sum is a sub-Laplacian $\Delta$ on $G$.

The Concept of Telicity in English, Romanian and Serbian
Romanian Journal of English Studies, 2020 Given that the notion of telicity was simply defined by English linguists as a situation which tends towards a goal, this paper will additionally explain and define telicity in the English language.

Dense-Timed Petri Nets: Checking Zenoness, Token liveness and Boundedness [PDF]
, 2007 We consider Dense-Timed Petri Nets (TPN), an extension of Petri nets in which each token is equipped with a real-valued clock and where the semantics is lazy (i.e., enabled transitions need not fire; time can pass and disable transitions).

, 2018 In the present paper, we will characterize the boundedness of the generalized fractional integral operators $I_{\rho}$ and the generalized fractional maximal operators $M_{\rho}$ on Orlicz spaces, respectively.

Computing the area-minimizing surface by the Allen-Cahn equation with the fixed boundary
AIMS Mathematics, 2023 The Allen-Cahn equation is a famous nonlinear reaction-diffusion equation used to study geometric motion and minimal hypersurfaces. This link has been scrutinized to construct minimal surfaces for many years.

The $\ell^s$-boundedness of a family of integral operators on UMD Banach function spaces
, 2018 We prove the $\ell^s$-boundedness of a family of integral operators with an operator-valued kernel on UMD Banach function spaces. This generalizes and simplifies earlier work by Gallarati, Veraar and the author, where the $\ell^s$-boundedness of this ...

Crystalline boundedness principle [PDF]
, 2005 We prove that an $F$-crystal $(M,\vph)$ over an algebraically closed field $k$ of characteristic $p>0$ is determined by $(M,\vph)$ mod $p^n$, where $n\ge 1$ depends only on the rank of $M$ and on the greatest Hodge slope of $(M,\vph)$.

Substitution and χ -boundedness
Journal of Combinatorial Theory, Series B, 2013 A class $\mathcal{G}$ of graphs is said to be {\em $\chi$-bounded} if there is a function $f:\mathbb{N} \rightarrow \mathbb{R}$ such that for all $G \in \mathcal{G}$ and all induced subgraphs $H$ of $G$, $\chi(H) \leq f(\omega(H))$. In this paper, we show that if $\mathcal{G}$ is a $\chi$-bounded class, then so is the closure of $\mathcal{G}$ under any
