On some properties of generalized Fibonacci polynomials
(Open Journal of Discrete Applied Mathematics, 2020)
Fibonacci polynomials have been generalized mainly by two ways: by maintaining the recurrence
relation and varying the initial conditions and by varying the recurrence relation and maintaining the
initial conditions. In ...
NOTIONS OF CONTINUITY FOR FINITE RANK MAPS IN THE SPACE OF NORMAL OPERATORS
(2020)
We show that a natural extension of a continuous finite rank operator to an arbitrary Hilbert space is continuous. We also give sufficient conditions to calculate delta- epsilon numbers in all the domains of T. In addition,
we ...
Comparative Analysis of Spectral Theory of Second Order Difference and Differential Operators with Unbounded Odd Coefficient
(KYUNGPOOK, 2020)
We show that selfadjoint operator extensions of minimal second order differ ence operators have only discrete spectrum when the odd order coefficient is unbounded
but grows or decays according to specific conditions. ...
Spectra of Composition Groups on the Weighted Dirichlet Space of the Upper Half-Plane
(Springer, 2020)
We prove that the group of weighted composition operators induced by contin uous automorphism groups of the upper half plane U is strongly continuous on the weighted
Dirichlet space of U, Dα(U). Further, we investigate ...
Norm Properties of S -Universal Operators
(Communications in Advanced Mathematical Sciences, 2020)
We investigate the norm properties of a generalized derivation on a norm ideal J in B(H), the algebra of
bounded linear operators on a Hilbert space H. Specifically, we extend the concept of S−universality from the
inner ...
Application of binary logistic regression model: determinants of contraceptive utilization.
(IJRAR, 2020)
Contraceptives uptake among the youth has been a sensitive and controversial issue in the society that has resulted to various
social problems that include unwanted pregnancies and sexual transmitted infections among ...
Refined enumeration of k-plane trees and k-noncrossing trees
(2022)
A k-plane tree is a plane tree whose vertices are assigned labels between 1 and k in such a way that the sum of the labels along any edge is no greater than k+1. These trees are known to be related to (k+1)-ary trees, and ...
Bijections of k-plane trees
(Open journal of discrete Applied Mathematics, 2022)
A k-plane tree is a tree drawn in the plane such that the vertices are labeled by integers in the set
{1, 2, . . . , k}, the children of all vertices are ordered, and if (i, j) is an edge in the tree, where i and j are ...
On the Numerical Solution of Boundary Value Problem (BVP) of the Ordinary Differential Equation (ODE) - The Case of Steady-State Bio-Heat Equation with Combined Heat Transfer Coefficient by Pseudo-Spectral Collocation Method
(European Journal of Engineering and Technology Research, 2023-09-15)
Spectral methods for the solution of a boundary value problem of an ordinary differential equation are reviewed with particular emphasis laid on pseudo-spectral collocation method. The pseudo-collocation method is then ...
Reachability in complete t-ary trees
(Annals of Mathematics and Computer Science, 2023-10-01)
Mathematical trees such as Cayley trees, plane trees, binary trees, noncrossing trees, t-ary trees among others have been studied extensively. Reachability of vertices as a statistic has been studied in Cayley trees, plane ...
