A combination of Lie groupbased high order geometric integrator and deltashaped basis functions for solving Kortewegde Vries (KdV) equation
(World Scientific Publication, 2021)In this work, we develop a novel method to obtain numerical solution of wellknown Kortewegde Vries (KdV) equation. In the novel method, we generate differentiation matrices for spatial derivatives of the KdV equation by ...

Local existence and blowup of solutions for coupled viscoelastic wave equations with degenerate damping terms
(Serbian Society of Mechanics, 2020)In this paper, we investigate a nonlinear system of viscoelastic equations with degenerate damping and source terms in a bounded domain. Under appropriate assumptions on the parameters, degenerate damping terms and the ... 
A local radial basis functionfinite difference (RBFFD) method for solving 1D and 2D coupled SchrödingerBoussinesq (SBq) equations
(Elsevier, 2021)In this study, onedimensional (1D) and twodimensional (2D) coupled SchrodingerBoussinesq (SBq) equations are examined numerically. A local meshless method based on radial basis functionfinite difference (RBFFD) method ... 
Mathematical behaviour of solutions of the Kirchhoff type equation with logarithmic nonlinearity
(American Institute of Physics Inc., 2019)In this work, we consider the Kirchhoff type equation with logarithmic nonlinearity. We obtain the global existence of the solutions by using the potential well method. 
New applications of the Bernardi integral operator
(MDPI AG, 2020)Let A(p, n) be the class of f (z) which are analytic pvalent functions in the closed unit disk U = {z ∈ C: z ≤ 1}. The expression Bmλf(z) is defined by using fractional integrals of order l for f (z) ∈ A(p, n). When ... 
A norm inequality for functions of Lp(.)(Ω) spaces
(Academic Publications Ltd., 2020)We prove an inequality in Lp(.)(Ω) that give a relation between norm of function and norm of function restriction to a partition of domain. 
Normalized dini functions connected with kUniformly convex and kStarlike functions
(Korean Soc Computational & Applied MathematicsKSCAM, 2021)The purpose of the present paper is to give sufficient conditions for normalized Dini function which is the special combination of the generalized Bessel function of first kind to be in the classes kstarlike functions and ... 
On certain subclasses of starlike and convex functions associated with Pascal distribution series
(TUBITAK, 2020)In this article, we introduced a new power series whose coefficients are probabilities of the Pascal distribution. We investigated new approaches between the Pascal distribution series and some subclasses of normalized ... 
On lambdapseudo bistarlike functions with respect to symmetric points associated to shelllike curves
(University of Kragujevac  Faculty of Science, 2021)In this paper we define a new subclass lambdapseudo bistarlike functions with respect to symmetric points of Sigma related to shelllike curves connected with Fibonacci numbers and determine the initial TaylorMaclaurin ... 
On strongly Ozaki biclosetoconvex functions
(TUBITAK, 2019)In this paper, we introduce and investigate a new subclass of strongly Ozaki biclosetoconvex functions in the open unit disk. We have also found estimates for the first two TaylorMaclaurin coefficients for functions ... 
On subclasses of biconvex functions defined by Tremblay fractional derivative operator
(BabesBolyai University, 2019)We introduce and investigate new subclasses of analytic and biunivalent functions defined by modified Tremblay operator in the open unit disk. Also we obtain upper bounds for the coefficients of functions belonging to these ... 
On the invariance of certain vanishing subspaces of Morrey spaces with respect to some classical operators
(Birkhauser, 2020)We consider subspaces of Morrey spaces defined in terms of various vanishing properties of functions. Such subspaces were recently used to describe the closure of C0∞(Rn) in Morrey norm. We show that these subspaces are ... 
Partially linear multivariate regression in the presence of measurement error
(Korean Statistical Society, 2020)In this paper, a partially linear multivariate model with error in the explanatory variable of the nonparametric part, and an m dimensional response variable is considered. Using the uniform consistency results found for ... 
Slant submersions in paracontact geometry
(Hacettepe University, 2020)In this paper, we investigate some geometric properties of three types of slant submersions whose total space is an almost paracontact metric manifold. © 2020, Hacettepe University. All rights reserved.
