INSERTION-OF-IDEAL-FACTORS-PROPERTY

open access: yesEast Asian mathematical journal, 2014
Abstract. Due to Bell, a ring R is usually said to be IFP if ab = 0implies aRb = 0 for a;b 2R. It is shown that if f(x)g(x) = 0 for f(x) =a 0 +a 1 x and g(x) = b 0 + +b n x n in R[x], then (f(x)R[x]) 2n+2 g(x) = 0.Motivated by this results, we study the structure of the IFP when properideals are taken in place of R, introducing the concept of insertion-

Modeling photoconversion efficiency of perovskite solar cells

open access: yes, 2017
A theoretical approach to photoconversion efficiency modeling in perovskite p-i-n structures is developed. The results of this modeling compare favorably with the experiment and indicate that the surfaces of the perovskite solar cells (SCs) are naturally

Factorization of complete ideals

open access: yesJournal of Algebra, 1988
Zariski developed a theory of complete ideals for two-dimensional regular local rings. He proved that in such rings there is unique factorization of complete ideals [\textit{O. Zariski}, Am. J.
