Modern machine learning techniques have become indispensable in many fields of astronomy and astrophysics. Here we introduce a specific class methods, invertible neural networks, discuss two applications, the prediction stellar parameters from photometric observations study feedback processes on emission lines.

Non-invertible symmetries have been extensively studied in quantum field theories recent years. In this note we initiate their study supergravity. We find infinite families of non-invertible defects 11d and 10d Type II supergravities. These operators display a rich action on different probe branes. comment how these are removed the UV completion, M-theory String Theory existence strengthens lin...

We discuss invertible and non-invertible topological condensation defects arising from gauging a discrete higher-form symmetry on higher codimensional manifold in spacetime, which we define as gauging. A $q$-form is called $p$-gaugeable if it can be gauged codimension-$p$ spacetime. focus 1-gaugeable 1-form symmetries general 2+1d QFT, gauge them surface The universal fusion rules of the result...

The spectra of signed matrices have played a fundamental role in social sciences, graph theory, and control theory. In this work, we investigate the computational problems of identifying symmetric signings of matrices with natural spectral properties. Our results are twofold: 1. We show NP-completeness for the following three problems: verifying whether a given matrix has a symmetric signing th...

The purpose of this paper is to interpret polynomial invariants of strongly invertible links in terms of Khovanov homology theory. To a divide, that is a proper generic immersion of a finite number of copies of the unit interval and circles in a 2-disc, one can associate a strongly invertible link in the 3-sphere. This can be generalized to signed divides : divides with + or sign assignment to ...
