Triangular matrix summability of a series
In this paper, in extending a result of Savas and Rhodes on indexed matrix summability, an analogue theorem has been established by using Euler-Totient function. Key words: Summability, triangular matrix summability, Euler-Totient function.
Approximation formulae for phase shifts of s–wave Schrödinger equation due to binomial potential and their applications
In this paper, we derive the approximation formulae for phase shifts of s-wave Schrödinger equation on introducing binomial potential function and then make their applications to study the fluctuations in the phase shift difference from the s-wave with respect to different values of the arbitrary parameter occurring in a given binomial potential function. Key words: S-wave...
Estimates for contraction oscillatory integral operators on Lp – spaces
In this study, we shall prove that the oscillatory integral operator can be reduced to the study of another contraction oscillatory integral operator, with a fixed point which leads to a sharp estimate. Key words: Oscillatory integrals operator, bilinear forms, Fourier transform, non singular matrix, intertwining.
Interval cut-set of interval-valued intuitionistic fuzzy sets
In this paper, different types of interval cut-set of interval-valued intuitionistic fuzzy sets (IVIFSs), complement of these cut-sets are defined. Some properties of those cut-set of IVIFSs are investigated. Also three decomposition theorems of IVIFSs are defined. These works can also be used in setting up the basic theory of IVIFSs. Key words: Interval-valued intuitionistic fuzzy sets,...
Knapsack problem: A case study of garden city radio (GCR), Kumasi, Ghana
Packing or arrangement problems form an integral part in a man’s life and cannot be out rightly ignored. Items need to be well arranged and protected to survive the move unscathed. When it is done efficiently, at least to its optimal level, space is saved. A room may become spacious when furniture, bags and other household items are arranged very well. The end result is beauty and attractiveness. Radio...
