Failure of the semi log canonical Abundance for compact K\"{a}hler threefolds

Swapnajit Das ยท 2026

In this article we show that the semi log canonical abundance for compact K\"ahler varieties fails in dimension $3$. More specifically we construct a counterexample of a compact K\"ahler (irreducible)โ€ฆ

Structural description of (bull, house)-free graphs

Manoj Belavadi, Chinh T. Hoang ยท 2026

The bull is a graph consisting of a triangle and two pendant edges. The P_5 is the chordless path on five vertices. The house is the complement of a P_5. A graph is k-critical if it is k-chromatic butโ€ฆ

Parameterization-driven arbitrary Lagrangian-Eulerian method for large-deformation isogeometric fluid-structure interaction

Jingya Li, Ye Ji, Hugo Verhelst, Henk den Besten, Matthias Moller ยท 2026

Body-fitted arbitrary Lagrangian-Eulerian (ALE) methods provide a sharp representation of the fluid-structure interface but rely on mesh-update strategies that incrementally deform a reference configuโ€ฆ

The maximum size of the partial ground set of skew Bollob\'{a}s systems

Yu Fang, Tao Feng, Xiaomiao Wang ยท 2026

A skew Bollob\'{a}s system $\mathcal{P}=\{(A_i,B_i):1\leq i\leq m\}$ is a collection of pairs of disjoint subsets of $[n]$ such that $A_i\cap B_j\ne\emptyset$ for any $1\leq i<j\leq m$. Denote by $S_1โ€ฆ

Operator-Valued Positivstellens\"atze on Matrix Convex Sets and Free Products of Finite Abelian Groups

Abhay Jindal, Igor Klep, Scott McCullough ยท 2026

We prove a Positivstellensatz for operator-valued noncommutative polynomials that are positive on matrix convex sets. Specifically, let $p$ be an operator-valued polynomial in $B(H)\otimes C<x>$ of deโ€ฆ

What is The Probability That A Random Graph With A Given Degree Sequence is Connected?

Louigi Addario-Berry, Bruce Reed, Dao Chen Yuan ยท 2026

An $n$-tuple $D=(d(1),\dots,d(n))$ is a \emph{feasible degree sequence} if there is a graph on $\{1,\dots,n\}$ such that $i$ has degree $d(i)$. Any such graph will have $m=\sum_{i=1}^n d(i)/2$ edges. โ€ฆ
