An optimal class of domains permitting inner boundaries in a divergence theorem for rough integrands
The divergence theorem on an open domain $U \subset \mathbb{R}^m$ of finite measure is investigated for the rough class $\mathcal{DM}_\infty(U)$ of bounded vector fields $u \, \colon \, U \to \mathbb{R}^m$ with a finite Radon measure divergence. Let $\mathcal{DB}(U)$ denote the closure of $\mathcal{DM}_\infty(U)$ in the Lebesgue space $L_\infty(U)$. Equivalent conditions are proved for the domain $U$ to admit the divergence theorem \begin{equation} \exists ! \ell \in \mathcal{DB}'(U) \, \colon …

Kamala Harris won the U.S elections: Bombshell report claims voting machines were tampered with before 202
Kamala Harris election tampering story raises new questions about the 2024 U.S. presidential election outcome. A quiet but major change to voting machines by Pro V&V—used in over 40% of U.S. counties—was never publicly reviewed or disclosed. Watchdog group SMART Elections flagged suspicious updates, missing votes, and statistical anomalies suggesting potential vote tampering. Now, a lawsuit is moving forward, challenging whether Kamala Harris may have actually won.

The Trump administration is preparing to begin the transfer of potentially thousands of foreigners who are in the United States illegally
to the U.S. military base in Guantšnamo Bay, Cuba,
starting as early as this week,
said U.S. officials familiar with the matter.

The foreign nationals under consideration hail from a range of countries.
They include hundreds from friendly European nations, including Britain, Italy, France, Germany, Ireland, Belgium, the Nethe…

Sombor index of clean graphs
Let $G = (V, E)$ be a graph with the vertex set $V (G)$ and edge set $E(G)$. The Sombor index of $G$, $SO(G)$, is defined as $\sum_{uv\in E(G)} \sqrt{deg(u)^2 + deg(v)^2}$, where $deg(u)$ is the degree of vertex $u$ in $V (G)$. The clean graph of a ring R, denoted by $Cl(R)$, is a graph with vertex set $\{(e, u) : e \in Id(R), u \in U(R)\}$ and two distinct vertices $(e, u)$ and$(f, v)$ are adjacent if and only if $ef = 0$ or $uv = 1$ ($Id(R)$ and $U(R)$ are the sets of idempotents and unit ele…

Existence of variational solutions to doubly nonlinear systems in general noncylindrical domains
We consider the Cauchy-Dirichlet problem to doubly nonlinear systems of the form \begin{align*} \partial_t \big( |u|^{q-1}u \big) - \operatorname{div} \big( D_ξf(x,u,Du) \big) = - D_u f(x,u,Du) \end{align*} with $q \in (0, \infty)$ in a bounded noncylindrical domain $E \subset \mathbb{R}^{n+1}$. Further, we suppose that $x \mapsto f(x,u,ξ)$ is integrable, that $(u,ξ) \mapsto f(x,u,ξ)$ is convex, and that $f$ satisfies a $p$-growth and -coercivity condition for some $p>\max \big\…
