High Relative Accuracy Computations With Covariance Matrices of Order Statistics

Mathematical Methods in the Applied Sciences, Volume 49, Issue 11, Page 11794-11810, 30 July 2026.
ABSTRACT In many statistical applications, numerical computations with covariance matrices need to be performed. The error made when performing such numerical computations increases with the condition number of the covariance matrix, which is related to the number of variables and the strength of the correlation between the variables. In a recent work,

Cyclic direct summands of modules [PDF]

, 1999
An open problem from the list of Eisenbud, cf. [DE] p. 367, connected with Groebner bases algorithm is the computation of the decomposition of module into direct summands.

Rigidity of non-negligible objects of moderate growth in braided categories

Forum of Mathematics, Pi
Let $\mathbb {k}$ be a field, and let $\mathcal {C}$ be a Cauchy complete $\mathbb {k}$ -linear braided category with finite-dimensional morphism spaces and . We call an indecomposable object X of $\mathcal C$ non-negligible if

On modules that complement direct summands

Osaka Journal of Mathematics, 1986
An R-module M is said to ''complement direct summands'' if for every direct summand B of M and for every decomposition \(M=\oplus_{i\in I}A_ i\), where every \(A_ i\) is completely incomposable, there exists a subset K of the index set I with \(M=B\oplus (\oplus_{k\in K}A_ k)\). The following characterizations are mentioned by \textit{M. Harada} [Publ.

Direct summands of klt singularities

Inventiones mathematicae
We show that direct summands (or more generally, pure images) of klt type singularities are of klt type. As a consequence, we give a different proof of a recent result of Braun, Greb, Langlois and Moraga that reductive quotients of klt type singularities are of klt type.

Closed ss-semilocal modules and rings

Open Mathematics
A module A is designated as closed ss -semilocal module provided for any closed submodule G of A, there exists a submodule H of A such that A = G + H and G ∩ H ≤ Soc s(A) where Soc s(A) = Rad(A) ∩ Soc(A) and a ring S is named as closed ss -semilocal ring

COATOMIC MODÜLLER VE SUMMAND TOPLAM ÖZELLIĞINE SAHIP MODÜLLER ARASINDAKI İLIŞKI ÜZERINE [PDF]

In this study, we investigate the structural interplay between two significant notions in module theory: coatomic modules and modules possessing the summand sum property (SSP).

On C. lifting and Semi*perfect Modules [PDF]

, 2015
In this paper, we introduce c. lifting module as a generalization of lifting module, we prove some results on c. lifting module, also we introduce semi*perfect module as a generalization of a semiperfect module and direct summand generalized* co-finitely
