The Eckardt point configuration of cubic surfaces revisited
(Springer, 2022)The classification problem for cubic surfaces with 27 lines is concerned with describing a complete set of the projective equivalence classes of such surfaces. Despite a long history of work, the problem is still open. One ... -
Unitals in projective planes of order 16
(Scientific Technical Research Council Turkey-Tubitak, 2021)In this study, we perform computer searches for unitals in planes of order 16. The number of known nonisomorphic unitals in these planes is improved to be 261. Some data related to 2- (65, 5, 1) designs associated with ... -
Controlling the Power-Law Fluid Flow and Heat Transfer Under the External Magnetic Field Using the Flow Index and the Hartmann Number
(World Scientific Publ Co Pte Ltd, 2020)The direct and optimal control solution of laminar fully developed, steady Magnetohydrodynamics (MHD) flow of an incompressible, electrically conducting power-law non-Newtonian fluid in a square duct is considered with the ... -
Novel explicit solutions for the nonlinear Zoomeron equation by using newly extended direct algebraic technique
(Springer, 2020)This paper presents an analytical solver which is known as a generalization of types methodologies. With the proposed method, one of the old but at the same time popular problem is considered, which is known as nonlinear ... -
The number of cubic surfaces with 27 lines over a finite field
(Springer, 2021)We determine the number of cubic surfaces with 27 lines over a finite field F-q. This is based on exploiting the relationship between non-conical six-arcs in a projective plane embedded in projective three-space and cubic ... -
Affine Factorable Surfaces in Isotropic Spaces
(Inst Applied Mathematics, 2020)In this paper, we study the problem of finding affine factorable surfaces in a 3-dimensional isotropic space I-3 with prescribed Gaussian (K) or mean (H) curvatures. Because the absolute figure of I-3, by permutation of ... -
Construction of Green's functional for a third order ordinary differential equation with general nonlocal conditions and variable principal coefficient
(Walter De Gruyter Gmbh, 2020)In this work, the solvability of a generally nonlocal problem is investigated for a third order linear ordinary differential equation with variable principal coefficient. A novel adjoint problem and Green's functional are ... -
Analytical study on the balancing principle for the nonlinear Klein-Gordon equation with a fractional power potential
(Elsevier B.V., 2020)In the literature, although many methods depend on the ansatz solution, there is not any specific rule to determine the degree of the ansatz i.e. balancing principle. The problem is especially seen with the fractional and ... -
Nonsingular cubic surfaces over F(2)k
(Scientific Technical Research Council Turkey-Tubitak, 2021)We perform an opportunistic search for cubic surfaces over small fields of characteristic two. The starting point of our work is a list of surfaces complied by Dickson over the field with two elements. We consider the ... -
On Generalized Constant Ratio Surfaces of Higher Codimension
(Springer Basel Ag, 2019)In this paper, we introduce constant slope (CS) and generalized constant ratio (GCR) submanifolds with higher codimension in Euclidean spaces. We firstly obtain a classification of GCR surfaces in Euclidean 4-spaces E4. ... -
On surfaces endowed with a canonical principal direction in Euclidean 4-spaces
(Scientific Technical Research Council Turkey-Tubitak, 2019)In this paper, we introduce canonical principal direction (CPD) submanifolds with higher codimension in Euclidean spaces. Then we obtain a classification of surfaces endowed with CPD relative to a fixed direction in Euclidean ... -
Polynomial Affine Translation Surfaces in Euclidean 3-Space
(Soc Paranaense Matematica, 2019)In this paper we study the polynomial affine translation surfaces in E-3 with constant curvature. We derive some non-existence results for such surfaces. Several examples are also given by figures. -
Weighted Harmonic Bloch Spaces on the Ball
(Springer Basel Ag, 2018)We study the family of weighted harmonic Bloch spaces , on the unit ball of . We provide characterizations in terms of partial and radial derivatives and certain radial differential operators that are more compatible with ... -
An Improved Analytical Solution of Population Balance Equation Involving Aggregation and Breakage via Fibonacci and Lucas Approximation Method
(Walter De Gruyter Gmbh, 2019)This study presents a novel analytical solution for the Population Balance Equation (PBE) involving particulate aggregation and breakage by making use of the appropriate solution(s) of the associated complementary equation ... -
Green's Functional for Higher-Order Ordinary Differential Equations with General Nonlocal Conditions and Variable Principal Coefficient
(Springer, 2019)The method of Green's functional is a little-known technique for the construction of fundamental solutions to linear ordinary differential equations (ODE) with nonlocal conditions. We apply this technique to a higher-order ... -
Maximal arcs in projective planes of order 16 and related designs
(Walter De Gruyter Gmbh, 2019)The resolutions and maximal sets of compatible resolutions of all 2-(120,8,1) designs arising from maximal (120,8)-arcs, and the 2-(52, 4, 1) designs arising from previously known maximal (52, 4)-arcs, as well as some newly ... -
New results on helix surfaces in the Minkowski 3-space
(Int Electronic Journal Geometry, 2019)In this paper, we characterize and classify helix surfaces with principal direction relatived to a space-like and light-like, constant direction in the Minkowski 3-space. -
A new approach for the black-scholes model with linear and nonlinear volatilities
(MDPI AG, 2019)Since financial engineering problems are of great importance in the academic community, effective methods are still needed to analyze these models. Therefore, this article focuses mainly on capturing the discrete behavior ... -
Spectral Analysis of Discontinuous Boundary-Value Problems with Retarded Argument

Population Balances Involving Aggregation and Breakage Through Homotopy Approaches
(Walter De Gruyter Gmbh, 2018)Homotopy techniques in nonlinear problems are getting increasingly popular in engineering practice. The main reason is because the homotopy method deforms continuously a difficult problem under study into a simple problem, ...
