Delta(m)-Statistical convergence
(INDIAN NAT SCI ACAD, 2001)In this paper, we define a general sequence space Delta (m) (X) = {x = (x(k)) : (Delta (m) x(k)) is an element of X}, (m is an element of N), where X is any sequence space. We establish some inclusion relations, topological ... -

DENSITY AND FINITENESS RESULTS ON SUMS OF FRACTIONS
(AMER MATHEMATICAL SOC, 2019)We show that the height density of a finite sum of fractions is zero. In fact, we give quantitative estimates in terms of the height function. Then, we focus on the unit fraction solutions in the ring of integers of a given ... -
A density functional study on the efficiencies of 2-mercaptobenzoxazole and its derivatives as chelating agents in flotation processes
(ELSEVIER SCIENCE BV, 2006)By using the density functional theory (DFT), we calculated some properties such as the energies of highest occupied molecular orbital (HOMO) orbitals and the atomic charges which are related to the reactive behavior of ... -
