Weak abelian direct summands and irreducibility of Galois representations
Let $\rho_\ell$ be a semisimple $\ell$-adic representation of a number field $K$ that is unramified almost everywhere. We introduce a new notion called weak abelian direct summands of $\rho_\ell$ and completely characterize them, for example, if the ...

Selforthogonal modules without obvious direct summands
, 2007 We describe a sufficient condition which explains the aboundance of many rather small, and not necessarily faithful, selforthogonal modules M with the following properties: (1)The projective (resp. injective) dimension of M is finite and bigger than 1

Modules, Lattices and Their Direct Summands [PDF]
, 1992 It is well known that any finitely generated Z-module is a direct sum of a projective (in fact a free) module and a Noetherian module (in fact a module of finite length) (for example see [Fu]). More generally, [Sm1] proved that if R is a right Noetherian

Sub-direct sums and positivity classes of matrices
, 1999 It is well known that a direct sum is positive semidefinite if and only if each of the direct summands is positive semidefinite. In fact, it is also known that this statement remains true if positive semidefinite is replaced with: doubly nonnegative ...

Modules Whose Submodules Are Essentially Embedded in Direct Summands
, 2009 WOS: 000263199400006A module M is said to satisfy the C-12 condition if every submodule of M is essentially embedded in a direct summand of M. It is known that the C-11 ( and hence also C-1) condition implies the C-12 condition. We show that the class of

Modules Whose Direct Summands Are Fi-Extending
, 2017 WOS: 000438053300008A module M is called FI-extending if every fully invariant submodule of M is essential in a direct summand of M. It is not known whether a direct summand of an FI-extending module is also FI-extending.
