Permutation Summands Over Z [PDF]
, 1994 A permutation lattice for a finite group G is a free Z-module with a finite basis which is permuted by G; direct summands of these, as ZG-module, are the lattices of the title.

Codes in Dihedral Group Algebra
Моделирование и анализ информационных систем, 2018 Robert McEliece developed an asymmetric encryption algorithm based on the use of binary Goppa codes in 1978 and no effective key attacks has been described yet.

MODULES WHOSE CERTAIN SUBMODULES ARE ESSENTIALLY EMBEDDED IN DIRECT SUMMANDS [PDF]
, 2016 It is well known that, if the ring has acc on essential right ideals, then for every quasi-continuous module over the ring, the finite exchange property implies the full exchange property.

Relative injectivity and CS-modules
International Journal of Mathematics and Mathematical Sciences, 1994 In this paper we show that a direct decomposition of modules M⊕N, with N homologically independent to the injective hull of M, is a CS-module if and only if N is injective relative to M and both of M and N are CS-modules. As an application, we prove that

Persistent Tensors and Multiqudit Entanglement Transformation [PDF]
QuantumWe construct a lower bound of the tensor rank for a new class of tensors, which we call $\textit{persistent tensors}$. We present three specific families of persistent tensors, of which the lower bound is tight.

Modules whose h-closed submodules are direct summands [PDF]
, 2020 This paper is based on the class of modules whose h-closed submodules are direct summands. We introduce and investigate the structural properties for the former class of modules and we elaborate our results with lifting ...

When some complement of an exact submodule is a direct summand [PDF]
, 2021 In this article, we study C-11(r)-modules. It is shown that the class of modules with property, each submodule such that the image of its quotient is zero under a left exact preradical has a complement which is a direct summand, is closed under direct ...

Stochastic Gradient Descent in High Dimensions for Multi‐Spiked Tensor PCA
Communications on Pure and Applied Mathematics, EarlyView.ABSTRACT We study the high‐dimensional dynamics of online stochastic gradient descent (SGD) for the multi‐spiked tensor model. This multi‐index model arises from the tensor principal component analysis (PCA) problem with multiple spikes, where the goal is to estimate the unknown signal vectors within the N$N$‐dimensional unit sphere through maximum ...

Anisotropy Factor Spectra for Weakly Allowed Electronic Transitions in Chiral Ketones
ChemPhysChem, Volume 26, Issue 6, March 15, 2025.Anisotropy factor spectra for the weak n→π*‐type A‐band of chiral ketones cannot be described within the Franck–Condon approximation. Thus, we present such spectra computed by accounting for Herzberg–Teller corrections and compare them to experiments for fenchone, camphor and 3MCP to describe chiroptical properties of these molecules in the mid to near
