On progressive wave solution for non-planar KDV equation in a plasma with q-nonextensive electrons and two oppositely charged ions
(Işık University Press, 2020)
In this paper, the ion-acoustic wave is investigated in a plasma with q-nonextensive electrons and two oppositely charged ions with varying masses. These parameters are found to modify the linear dispersion relation and ...
Identities and relations on the hermite-based tangent polynomials
(Işık University Press, 2020)
In this note, we introduce and investigate the Hermite-based Tangent numbers and polynomials, Hermite-based modified degenerate-Tangent polynomials, polyTangent polynomials. We give some identities and relations for these ...
Numerical treatment of newell-whitehead-segel equation
(Işık University Press, 2020)
In this paper, a comparative study of recently developed numerical methods in solving nonlinear Newell-–Whitehead—Segel equations is carried out. Results computed using Variational iteration method (VIM) are compared with ...
Existence and uniqueness of an inverse problem for a wave equation with dynamic boundary condition
(Işık University Press, 2020)
In this paper, an initial boundary value problem for a wave equation with dynamic boundary condition is considered. Giving an additional condition, a timedependent coefficient is determined and existence and uniqueness ...
Hypersurfaces of a finsler space with deformed berwald-infinite series metric
(Işık University Press, 2020)
The rationale of this paper is to study the Finslerian hypersurfaces of a Finsler space with the special deformed Berwald-Infinite series metric. Further examined under which condition, the Finslerian hypersurfaces of this ...
Bounds for initial maclaurin coefficients for a new subclasses of analytic and M-fold symmetric BI-univalent functions
(Işık University Press, 2020)
In the present paper, we introduce and study two new subclasses of the function class ?m consisting of analytic and m-fold symmetric bi-univalent functions in the open unit disk U. We establish upper bounds for the initial ...
On some integral inequalities for (s, m)-convex functions
(Işık University Press, 2020)
A new identity has been handled in this paper. It allows to derive new inequalities referring to upper estimation of the Jensen functional in the class of (s, m)- convex functions. Also some applications for special means ...
Even vertex odd mean labeling of transformed trees
(Işık University Press, 2020)
Let G = (V;E) be a graph with p vertices and q edges. A graph G is said have an even vertex odd mean labeling if there exists a function f: V (G) →{0; 2; 4;:::; 2q} satisfying f is 1-1 and the induced map f*: E(G) → {1; ...
On a class of p(x)-Kirhhoff type problems with Robin boundary conditions and indefinite weights
(Işık University Press, 2020)
In this paper, we consider a class of p(x)-Kirhhoff type problems with Robin boundary conditions and indefinite weights. Under some suitable conditions on the nonlinearities, we establish the existence of at least one ...
Fourth-order accurate method based on half-step cubic spline approximations for the 1d time-dependent quasilinear parabolic partial differential equations
(Işık University Press, 2020)
In this article, we discuss a fourth-order accurate scheme based on cubic spline approximations for the solution of quasilinear parabolic partial differential equations (PDE). The stability of the scheme is discussed using ...
