Generalized centroid of G-semirings
(Universidad Catolica del Norte, 2018)We define and study the generalized centroid of a semiprime ?- semiring. We show that the generalized centroid C ? is a multiplicatively reguler ?-semiring and so ?-semifield and give some properties of the generalized ... -
Spectra and fine spectra for the upper triangular band matrix U (a 0 , a 1 , a 2 ; b 0 , b 1 , b 2 ) over the sequence space c 0
(Universidad Catolica del Norte, 2019)The aim of this paper is to obtain the spectrum, fine spectrum, approximate point spectrum, defect spectrum and compression spectrum of the operator on the sequence space c 0 where b 0 , b 1 , b 2 are nonrzero and the ...
