I like my ladies like i like my assumptions on almost minimal Fano varieties.
Screenshot of LaTeX editor:

(begin (proposition}
(labelfprop-nonempty}
[Prokhorox, Icite[Thm. 1.15]{MR4922010}]
Suppose that $V$ is a Fano $n$-fold of index $d \geq n-2$. Then $|-K_V| Ineq lemptyset$.
lend(proposition}
응
At present, the general non-emptiness of $|-K_VI$ for higher dimensional Fano varieties of low index is not known to the best of our knowledge.
This leads us to the following critical assumption that we use throughout the remainder of the article.
%
(begin (assumption)
(label fass-nonempty}
Let $V$ be an almost minimal Fano $n$-fold.
Then $|-K_V| \neq lemptyset$, and a general, smooth, irreducible divisor $X^\vee lin I-K_V|$ is a CY variety.
lend {assumption}
응
\par In the context of this article, a CY xacietx of dimension $m$ is a smooth xaciety of dimension with trivial canonical class and
$h^{i,0}=0$ for $i = 1,\dots, m-1$. Such a variety
may be closed (resp. open), and hence projective (resp. quasiprojective). Given our assumptions, associated to a Fano $n$-fold $V$ are two natural CY varieties of respective dimension $n-1, l, n+1$:
$X^\vee lin |-K_V|$, a very general smooth

New paper that studies the interplay between how light is deflected by electrically charged black holes and the geometry of a special family of elliptic fibrations hit the timeline last night! 🥳✨ arxiv.org/abs/2609.30730
A visualization of a black hole with various parts labelled.Screenshot of the article. Title: Photon spheres, elliptic surfaces, and Seiberg Witten geometry
Abstract: We study null geodesics in Reissner-Nordström-de Sitter spacetime and in its w =
-2/3 Kiselev deformation through the elliptic curves defined by the radial equation. The relation of these curves to the non-critical E- Seiberg- Witten family yields differential equations for finite-distance light deflection, and explains the boundary source term through a suitable gauge of the Seiberg Witten differential. This geometry separates
the extremal point Q = M2 from the Argyres-Douglas point Q2 = 9M2/8. We also
determine the Kiselev critical and horizon loci, and show that, at fixed nonzero angular momentum, the Argyres-Douglas and ultracold loci meet only at zero Killing energy.

Coming soooooon to a timeline near you.

Abstract: We study null geodesics in Reissner Nordström de Sitter spacetime and its w = -2/3
Kiselev deformation using the elliptic curves defined by the radial equation.
Their
relation to the non-critical Er Seiberg Witten family yields differential equations for finite-distance light deflection and explains the boundary source through a suitable gauge of the Seiberg Witten differential. This geometry separates the extremal point Q = Mº from the Argyres Douglas point Q = 9M-/8.
We also determine the Kiselev
critical and horizon loci and show that, at fixed nonzero angular momentum, the Argyres Douglas and ultracold loci meet at zero Killing energy.

The JUNO detector, a huge sphere full of 20,000 tonnes of transparent organic goop, is detecting antineutrinos produced by two nuclear reactors each located the same distance away. After just 2 months, it measured some things about neutrino masses better than ever before! Let's dig in. (1/13)
