$J$-class weighted translations on locally compact groups
A bounded linear operator $T$ on a Banach space $X$ (not necessarily separable) is said to be $J$-class operator whenever the extended limit set, say $J_T(x)$ equals $X$ for some vector $x\in X$. Practically, the extended limit sets localize the dynamical behavior of operators. In this paper, using the extended limit sets we will examine the necessary and sufficient conditions for the weighted translation $T_{a,ω}$ to be $J$-class on a locally compact group $G$, within the setting of $ L^p$-sp…

Implications of a turbulent convection model for classical Cepheids
The appearance of blue loops in the evolutionary tracks of intermediate-mass core He-burning stars is essential for explaining the observed characteristics of Cepheids. The blue loops for lower mass Cepheids cannot always be reproduced when only classical, local mixing length theory (MLT) is used. Additionally, classical models result in a mass discrepancy compared to pulsational and dynamical mass determinations. Both problems can be resolved through an ad-hoc extension of the MLT for convecti…

“From Catalunya in the northeast to Andalusia in the southwest of Spain, she overcame local differences, building solidarity among anarcho-syndicalists whose strength really lay in local and regional councils. She had the capacity to speak to a crowd as if she were talking to friends in a café, and reached equally the male and female working class. A natural teacher, she understood and could explain how particular struggles fit into larger campaigns… she was one of those mythical organizers …

Unrolling Nonconvex Graph Total Variation for Image Denoising
Conventional model-based image denoising optimizations employ convex regularization terms, such as total variation (TV) that convexifies the $\ell_0$-norm to promote sparse signal representation. Instead, we propose a new non-convex total variation term in a graph setting (NC-GTV), such that when combined with an $\ell_2$-norm fidelity term for denoising, leads to a convex objective with no extraneous local minima. We define NC-GTV using a new graph variant of the Huber function, interpretable …

My question about the PTSN switch-off campaign is: can BT not already *detect* (over the course of a year) which customers are using alarms or telecare devices likely to be impacted?

Boundaries and equivariant maps for ergodic groupoids
We give a notion of boundary pair $(\mathcal{B}_-,\mathcal{B}_+)$ for measured groupoids which generalizes the one introduced by Bader and Furman \cite{BF14} for locally compact groups. In the case of a semidirect groupoid $\mathcal{G}=Γ\ltimes X$ obtained by a probability measure preserving action $Γ\curvearrowright X$ of a locally compact group, we show that a boundary pair is exactly $(B_- \times X, B_+ \times X)$, where $(B_-,B_+)$ is a boundary pair for $Γ$. For any measured groupoid $(…

SCOTUS majority appears likely to OK nation's first religious charter school
A ruling for Oklahoma's charter school board would further increase the role of religion in public life — and change public education in America.
