On products of abelian skew braces
The main objective of this paper is to study factorisations of skew left braces through abelian subbraces. We prove a skew brace theoretical analog of the classical Itô's theorem about product of two abelian groups: if $B = A_1A_2$ is a skew brace which is the product of two abelian skew subbraces $A_1$ and $A_2$, and $A_1$ is a left and right ideal of $B$, then the commutator ideal $[B, B]^B$ of $B$ is an abelian brace. If $A_1$ is a left (non-necessarily right) ideal of $B$, we show that the…

“Noor, who made so many friends on Bluesky since she started an account there in the summer of 2023, had her account suddenly suspended on Friday. Bluesky did not send a reason for the suspension, so while she wrote an appeal, she did not know what actions she was appealing, so as of now it's still suspended. She’s been silenced, and effectively disappeared.”

A Future for Noor and Her Children
Hello! I'm Meave, a U.S. citizen sponsoring this fundraiser on behalf of my dear friend Noor Hassan and her children. Noor and her son Abdul Rahman are kind, generous people; though their original fundraiser succeeded last summer, supporting themselves and their extended family cost them everything. This fundraiser will allow them to support themselves and save up to buy passage to Egypt and pursue a better future.

Non-Abelian orbifolds of the SO(32) heterotic string
Non-Abelian toroidal heterotic orbifolds have received comparatively little attention, mainly because of the significant computational challenges they pose, even at the level of computing their matter spectrum. Similarly, the SO(32) heterotic string remains relatively unexplored. In this paper, we provide some useful tools to handle this situation. We find that certain non-Abelian orbifolds can be studied using the techniques that are common to Abelian compactifications. In such cases, we show …

Cycles on abelian 2n-folds of Weil type from secant sheaves on abelian n-folds
A. Weil identified a 2-dimensional space of rational classes of Hodge type (n,n) in the middle cohomology of every 2n-dimensional abelian variety with a suitable complex multiplication by an imaginary quadratic number field. These abelian varieties are said to be of Weil type and these Hodge classes are known as Weil classes. We prove that the Weil classes are algebraic for all abelian sixfold of Weil type of discriminant -1, for all imaginary quadratic number fields. The algebraicity of the We…
