Reflexive dg categories in algebra and topology

Reflexive dg categories in algebra and topology
Reflexive dg categories were introduced by Kuznetsov and Shinder to abstract the duality between bounded and perfect derived categories. In particular this duality relates their Hochschild cohomologies, autoequivalence groups, and semiorthogonal decompositions. We establish reflexivity in a variety of settings including affine schemes, simple-minded collections, chain and cochain dg algebras of topological spaces, Ginzburg dg algebras, and Fukaya categories of cotangent bundles and surfaces as …

"Twelve years after “As We May Think”, and simultaneous with the developments of the IBM 1401 and FORTRAN, copies of “Datamation” started popping up on selected newsstands. This magazine was the godfather of all programming magazines, and held its crown for 41 years (quite a few ages in computer time!), until being phased out as an online magazine in February 1998."

As We May Never Think Again
In 2010, a popular Argentine novelist, screenwriter, and blogger based in Spain called Hernán Casciari, got tired of dealing with publishing houses, editors, and mainstream media. He wanted to publish a magazine, but of a different kind. His idea of a magazine had very-well defined boundaries: high-quality content, no advertising, direct sales to the readers, and a luxury printed format. Against all odds, his idea worked: "Revista Orsai", kicked off as an experiment, and then became a staple a…

Vector-valued Graph Signal Processing
Classical graph signal processing (GSP) introduces methodologies for analyzing real or complex signals defined on graph domains, moving beyond classical uniform sampling techniques, such as the graph discrete Fourier transform (GDFT), employed as a pivotal tool for transforming graph signals into their spectral representation, enabling effective signal processing techniques such as filtering and denoising. In this paper, we propose a possible generalization of the set of signals and we study so…
