Serial Rings
A module is called uniseriat if it has a unique composition series of finite length. A ring (always with 1) is called serial if its right and left free modules are direct sums of uniserial modules. Nakayama, who called these rings generalized uniserial rings, proved [21, Theorem 171 that every finitely generated module over a serial ring is a direct sum of uniserial modules. In section one we g...
متن کاملThe Structure of Serial Rings
A serial ring (generalized uniserial in the terminology of Nakayama) is one whose left and right free modules are direct sums of modules with unique finite composition series (uniserial modules.) This paper presents a module-theoretic discussion of the structure of serial rings, and some onesided characterizations of certain kinds of serial rings. As an application of the structure theory, an e...
متن کاملPure-injective Modules over Right Noetherian Serial Rings
We give a criterion for the existence of a super-decomposable pure-injective module over an arbitrary serial ring.
متن کاملSerial Correlation Coefficient
In this paper, we investigate the relation between two variables where the one is measured with the ratio or interval scale and the other with the nominal. In this cases, we use from serial correlation coefficient. Computation of some serial coefficient such as biserial and point-biserial coefficient is carried out with some examples and R program.
متن کاملRings of Cross-striated Fibrils within the Cot Cone Pedicle: A Computer-assisted Serial EM Analysis
Using serial electron micrographs and a computer reconstruction system the authors have examined the three-dimensional cytoarchitecture of the cat cone pedicle. These reconstructions reveal that within each pedicle is a closed 4-6 Mm diameter ring of cross-striated fibrils similar to the nonring structures described in photoreceptor inner and outer segments by others in guinea pig, rat, chick, ...
