ON STRUCTURE AND COMMUTATIVITY OF NEAR - RINGS
(Universidad Católica del Norte, Departamento de Matemáticas, 2000)
Multiple split-ring resonators for tri-band filter with asymmetric response
(Scopus, 2011)
A triple-band filter composed of multiple split ring resonators is presented. This filter is based on a chain of triple split ring resonators that produces three pass-bands. The change in the dimensions of the corresponding ...
Galois orders in skew monoid rings
(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2010)
We introduce a new class of noncommutative rings - Galois orders, realized as certain subrings of invariants in skew semigroup rings, and develop their structure theory. The class of Calms orders generalizes classical ...
Non-commutative reduction rings
(Universidad Nacuional de Colombia; Sociedad Colombiana de matemáticas, 1999)
Reduction relations are means to express congruences on rings. In the special case of congruences induced by ideals in commutative polynomial rings, the powerful tool of Grabner bases can be characterized by properties of ...

Analysing the new Saturnian rings, R/2004 S1 and R/2004 S2
(Springer, 2005-12-01)
The Cassini-Huygens arrival into the Saturnian system brought a large amount of data about the satellites and rings. Two diffuse rings were found in the region between the A ring and Prometheus. R/2004 S1 is coorbital to ...
