[PDF][PDF] Complex matrix inversion via real matrix inversions

Z Dai, LH Lim, K Ye - arXiv preprint arXiv:2208.01239, 2023 - stat.uchicago.edu
We study the inversion analog of the well-known Gauss algorithm for multiplying complex
matrices. A simple version is (A+ iB)− 1=(A+ BA− 1B)− 1− iA− 1B (A+ BA− 1B)− 1 when A is …

On the effective version of Serre's open image theorem

J Mayle, T Wang - Bulletin of the London Mathematical Society, 2024 - Wiley Online Library
Abstract Let E/QE/Q be an elliptic curve without complex multiplication. By Serre's open
image theorem, the mod ℓ ℓ Galois representation ρ¯ E, ℓ ρ_E,ℓ of EE is surjective for each …

Power values of power sums: a survey

N Coppola, M Curcó-Iranzo, M Khawaja, V Patel… - Women in Numbers …, 2024 - Springer
Research on power values of power sums has gained much attention of late, partially due to

Modularity of special motives of rank four associated with Calabi-Yau threefolds

K Bönisch - 2023 - bonndoc.ulb.uni-bonn.de
In this thesis, we study modularity properties of pure motives and mixed period matrices of
rank four. The pure motives that we consider are associated with Calabi-Yau threefolds …

Motivic action for Siegel modular forms

A Horawa, K Prasanna - arXiv preprint arXiv:2307.04115, 2023 - arxiv.org

modular forms $ f $ of low weight on ${\rm GSp}(4) $ Shimura varieties. Inspired by the work …

Vign\'eras orbifolds: isospectrality, regulators, and torsion homology

A Bartel, A Page - arXiv preprint arXiv:2407.07240, 2024 - arxiv.org
We develop a new approach to the isospectrality of the orbifolds constructed by Vign\'eras.
We give fine sufficient criteria for i-isospectrality in given degree i and for representation …

Prolongement analytique de fonctions et de fonctions
