Extension Theory and the Classification of Fermionic Strongly Fusion 2-Categories (with an Appendix by Thibault Didier D'ecoppet and Theo Johnson-Freyd)
This paper presents a homotopy theoretic classification of fermionic strongly fusion 2-categories using the concept of group graded extensions.
Analysis of Scalar Fields with Series Convolution: A Study of the Deformed Double-Confluent Heun Equation
The article presents a series solution approach for the "deformed" double-confluent Heun equation, which arises from the radial part of the Klein-Gordon equation in the background of the Nutku-Ghezelbash-Kumar metric. The method involves the convolution of series expansions to handle the non-polynomial coefficients in the equation.
Efficient Computation of Spectra and Pseudospectra for Infinite-Volume Operators from Local Patches
The authors present a general algorithm to compute the spectrum and pseudospectrum of short-range, discrete, infinite-volume operators with finite local complexity, with rigorous error control.
