Abelian Groups and Regular Modules

Mathematical Notes, 2001
By the word module it is always meant a unitary left module over an associative ring with identity element and all groups are Abelian. A module is said to be regular if any of its cyclic submodules is a direct summand and a group is called endoregular if it is regular as a module over its endomorphism ring.

Modules with Regular Singularities on a Curve

Journal of the London Mathematical Society, 1989
Let k be an algebraically closed field of characteristic zero and \({\mathcal O}\) the ring of formal and convergent power series in one variable over k. Let \(A\subset {\mathcal O}\) be a k-subalgebra such that \(\dim _ k{\mathcal O}/A\) is finite.

REGULAR SINGULARITY OF DRINFELD MODULES

International Journal of Mathematics, 1994
Let \(\mathbb{F}_ q\) be the finite field with \(q=p^ n\) elements. Let \(K\) be a field containing \(\mathbb{F}_ q\) and let \(\tau: K\to K\) be the map \(x\mapsto x^ q\). So \(\tau\) gives rise to an embedding of \(K\) into itself which is surjective if and only if \(K\) is perfect. Let \(\overline {K}\) be a fixed algebraic closure of \(K\) with the

The Jacobson Radical and Regular Modules

Canadian Mathematical Bulletin, 1975
Let A be an associative, but not necessarily commutative, ring with identity, and J = J(A) its Jacobson radical. A (unital) module is regular iff every submodule is pure (see (1)). The regular socle R(M) of a module M is the sum of all its submodules which are regular. These concepts have been introduced and studied in (2).

Regular multiplication modules

Periodica Mathematica Hungarica, 1995
This paper deals with the following two properties of a module \(M\) over a commutative ring \(R\) [see \textit{T. Cheatham} and \textit{E. Enochs}, Math. Jap. 26, 9-12 (1981; Zbl 0466.16013)]: \(F\) regularity (i.e., each submodule of \(M\) is pure); \(\mathbb{Z}\) regularity (i.e., for each \(m\in M\) there is a homomorphism \(\ell:M\to \mathbb{R ...

Regular geometries for folded optical modules

Applied Optics, 1995
We present three new three-dimensional right-cylindrical folded modular interconnection architectures. To compare these systems among each other and with earlier designs, we introduce several figures of merit. The figures of merit describe such aspects of the system as the compactness, the relative angles of the optical axis to optical elements in the ...
