Feebly lifting modules [PDF]

Journal of Mahani Mathematical Research
In this article feebly lifting modules are defined. A module $W$ is called feebly lifting provided, for each fully idempotent $N\leq W$ there exists a direct summand $D\leq W$ providing $D\leq N$ and $\frac{N}{D}\ll \frac{W}{D}$.

⊕-s-extending modules

Ibn Al-Haitham Journal for Pure and Applied Sciences, 2020
     The -s-extending modules will be purpose of this paper, a module M  is -s-extending if each submodule in M is essential in submodule has a supplement that is direct summand.

Hereditary Properties of Direct Summands of Algebras [PDF]

Mathematical Research Letters, 1999
For an algebra, \(R\), the authors investigate the property, which they call FCR, saying that any finite-dimensional representation is completely reducible and that each element of the algebra acts non-zero on some finite-dimensional representation.

On construction of the canonical form on the frame bundle

Дифференциальная геометрия многообразий фигур, 2023
The detailed description of the construction of the canonical form on the higher order frame bundle over an n-dimensional smooth manifold is given. In particular, it is shown that some vector space isomorphism play­ing the key role in this construction ...

Direct summands of direct products of slender modules [PDF]

Pacific Journal of Mathematics, 1985
Suppose \(P=\prod_{I}G_ i\) is a direct product of slender R-modules. If \(| I|\) is non-measurable and A is a direct summand of P, then \(A=\prod_{J}A_ j\) where each \(A_ j\) is isomorphic to a direct summand of a countable direct product of \(G_ i's\).

A generalization of modules with the property (P*) [PDF]

Mathematica Moravica, 2017
I.A- Khazzi and P.F. Smith called a module M have the property (P*) if every submodule N of M there exists a direct summand K of M such that K ≤ N and N K C Rad(M K).

Projective covers and minimal free resolutions

International Journal of Mathematics and Mathematical Sciences, 1996
Using a generalization of the definition of the projective cover of a module, a special type of surjective free resolution, known as the projective cover of a complex, may be defined.

On connections on principal bundles

Arab Journal of Mathematical Sciences, 2017
A new construction of a universal connection was given in Biswas, Hurtubise and Stasheff (2012). The main aim here is to explain this construction. A theorem of Atiyah and Weil says that a holomorphic vector bundle E over a compact Riemann surface admits

Modules which are self-p-injective relative to projection invariant submodules

Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2017
In this article, we focus on modules M such that every homomorphism from a projection invariant submodule of M to M can be lifted to M. Although such modules share some of the properties of PI -extending (i.e., every projection invariant submodule is ...

Bayesian clustering of multivariate extremes

Canadian Journal of Statistics, EarlyView.
Abstract The asymptotic dependence structure between multivariate extreme values is fully characterized by their projections on the unit simplex. Under mild conditions, the only constraint on the resulting distributions is that their marginal means must be equal, which results in a nonparametric model that can be difficult to use in applications ...
