Remarks on the non-local eigenvalue problems for the p-Laplacian

Boundary Value Problems
We consider the p-Laplace eigenvalue problem − Δ p u = λ | u | q , w p − q w ( x ) | u | q − 2 u in Ω , u = 0 on ∂ Ω , $$ -\Delta _{p} u=\lambda |u|_{q, w}^{p-q} w(x)|u|^{q-2} u \quad {\text{in}} \ \Omega , \qquad u=0 \quad {\text{on}}\ \partial \Omega ,

A lower bound for the least eigenvalue of Δ+V

Manuscripta Mathematica, 1990
Let \(M^ n\) be a closed n dimensional Riemannian manifold, let \(\Delta\) be the scalar Laplacian, and let V: \(M\to {\mathbb{R}}\) be continuous. The author gives a sufficient condition for \(\Delta +V\) to be positive in terms of geometric assumptions on M; the author also gives an application to a Bochner type vanishing theorem.

An Integrated and Robust Deep Learning Framework for Denoising and Analyzing Single‐Cell Spatial Transcriptomics

Advanced Intelligent Systems, EarlyView.
Single‐cell Spatial Transcriptomics Analysis and Denoising Engine is introduced as a unified deep learning framework that jointly performs denoising, clustering, and gene prioritization in spatial transcriptomics. By integrating linear and nonlinear representations within a dual‐channel architecture, it improves robustness and accuracy, uncovers ...

A recursive construction of the regular exceptional graphs with least eigenvalue -2 [PDF]

, 2014
In spectral graph theory a graph with least eigenvalue 2 is exceptional if it is connected, has least eigenvalue greater than or equal to 2, and it is not a generalized line graph.

Public Attitudes Toward Compassionate Release of Older People From Prison: Findings From a National Survey in Australia

Australian Journal of Social Issues, EarlyView.
ABSTRACT The rapid increase in older people in prison populations worldwide is generating significant health, cost, and human rights pressures on custodial systems. Compassionate release for older, frail inmates is a potentially effective response, yet little is known about public support for this approach.

Non-geometric distance-regular graphs of diameter at least $3$ with smallest eigenvalue at least $-3$ [PDF]

In this paper, we classify non-geometric distance-regular graphs of diameter at least $3$ with smallest eigenvalue at least $-3$. This is progress towards what is hoped to be an eventual complete classification of distance-regular graphs with smallest ...

Existence of solutions to a third-order multi-point problem on time scales

Electronic Journal of Differential Equations, 2007
We are concerned with the existence and form of solutions to nonlinear third-order three-point and multi-point boundary-value problems on general time scales.

New techniques for old bones: Morphometric and diffeomorphometric analysis of the bony labyrinth of the Reilingen and Ehringsdorf Neandertals

The Anatomical Record, EarlyView.
Abstract Neandertals are known to possess very distinctive traits in their bony labyrinth morphology, such as an inferiorly positioned posterior canal and a very low number of turns in the cochlea. Hence, the inner ear has been often used to assess the Neandertal status of fragmentary fossils.
