Pair-Rich Corona of an Accreting Kerr Black Hole

Jonathan Zhang, Christopher Thompson ยท 2026

We build a self-consistent model of a warm scattering corona near an accreting black hole in Kerr geometry, in the regime of slow ($\sim 0.01$ Eddington) mass accretion. An iterative Monte Carlo proceโ€ฆ

Sharp Criteria for the existence of positive solutions to Lane-Emden-type inequalities on weighted graphs

Qingsong Gu, Lu Hao, Xueping Huang, Yuhua Sun ยท 2026

We study positive solutions of Lane--Emden-type inequalities on infinite, connected, locally finite weighted graphs. For arbitrary connected domains (with Dirichlet boundary when present), we establisโ€ฆ

On the Average-Case Performance of Greedy for Maximum Coverage

Eric Balkanski, Jason Chatzitheodorou, Flore Sentenac ยท 2026

For the classical maximum coverage problem, the greedy algorithm achieves a worst-case $1-1/e$ approximation, which is optimal unless $\text{P} = \text{NP}$. The notion of coverage appears in a wide rโ€ฆ

A rational model for the fiberwise THH transfer II: $A_\infty$-algebras

Florian Naef, Robin Stoll ยท 2026

In Part I, we proved that a rational model for the fiberwise THH transfer of a map $f$ of fibrations over a base space is given by the Hochschild homology transfer of a cdga model of $f$. In this papeโ€ฆ

Polynomial Kernels for Spanning Tree with Diversity Requirements

Petr A. Golovach, Diptapriyo Majumdar, Saket Saurabh ยท 2026

Given a connected undirected graph $G$, a spanning tree is a subgraph $T$ of $G$ such that $V(T) = V(G)$ and $T$ is a tree. A collection of $\ell$ spanning trees $T_1,\ldots,T_\ell$ is pairwise $k$-diโ€ฆ
