Discontinuity at fixed points with applications
(Belgian Mathematical Soc Triomphe, 2019)In this paper, we study new contractive conditions which are strong enough to generate fixed points but which do not force the map to be continuous at fixed points. In this context, we give new results on the fixed-circle ... -
Some theorems of approximation theory in weighted smirnov classes with variable exponent
(Springer Heidelberg, 2020)Let G. C be a Jordan domain with rectifiable Dini smooth boundary G. In this work, we investigate approximation properties of matrix transforms constructed via Faber series in weighted Smirnov classes with variable exponent. ... -
Certain combinatoric convolution sums arising from bernoulli and euler polynomials
(Univ Miskolc Inst Math, 2019)In this study, we introduce the absolute Mobius divisor function U (n). According to some numerical computational evidence, we consider integer pairs (n, n + 1) satisfying; phi (n) = phi (n + 1) = U (n) = U (n + 1). ... -
Fractional order model of immune cells influenced by cancer cells
(Edp Sciences S A, 2019)In this paper, we study the mathematical model of interaction cancer cells and immune system cells presented Castiglione and Piccoli. As the interaction between cancer cells and the immune system is weak, when the immune ... -
Local generalization of transversality conditions for optimal control problem
(Edp Sciences S A, 2019)In this paper, we introduce the transversality conditions of optimal control problems formulated with the conformable derivative. Since the optimal control theory is based on variational calculus, the transversality ... -
Analysis of advective-diffusive transport phenomena modelled via non-singular mittag-leffler kernel
(Edp Sciences S A, 2019)In this study, a linear advection-diffusion equation described by Atangana-Baleanu derivative with non-singular Mittag-Leffler kernel is considered. The Cauchy, Dirichlet and source problems are formulated on the half-line. ... -
A new contribution to discontinuity at fixed point
(House Book Science-Casa Cartii Stiinta, 2019)The aim of this paper is to obtain new solutions to the open question on the existence of a contractive condition which is strong enough to generate a fixed point but which does not force the map to be continuous at the ... -
Commutator subgroups of the power subgroups of generalized Hecke groups
(Luhansk Taras Shevchenko Natl Univ, 2019)Let p, q >= 2 be relatively prime integers and let H p, q be the generalized Hecke group associated to p and q. The generalized Hecke group H-p,H-q is generated by X (z) = - (z - lambda(p))(-1) and Y (z) = -(z + lambda(q))(-1) ... -
Approximation by norlund and riesz means in weighted lebesgue space with variable exponent
(Ankara Univ, 2019)We investigate the approximation properties of Norlund and Riesz means of trigonometric Fourier series are investigated in the subset of weighted Lebesgue space with variable exponent. -
Maximal convergence of faber series in smirnov-orlicz classes
(Univ Prishtines, 2019)It is known that Faber series are used for solving many problems in mechanical science, such as the problems on the stress analysis in the piezoelectric plane and the problems on the analysis of electro-elastic fields and ... -
Fixed-disc results via simulation functions
(Scientific Technical Research Council Turkey-Tubitak, 2019)In this paper, our aim is to obtain new fixed-disc results on metric spaces. To do this, we present a new approach using the set of simulation functions and some known fixed-point techniques. We do not need to have some ... -
Minimal free resolutions of the tangent cones for Gorenstein monomial curves
(Scientific Technical Research Council Turkey-Tubitak, 2019)We study the minimal free resolution of the tangent cone of Gorenstein monomial curves in affine 4-space. We give the explicit minimal free resolution of the tangent cone of noncomplete intersection Gorenstein monomial ... -
On C-parallel legendre curves in non-sasakian contact metric manifolds
(Univ NIS, 2019)In (2n + 1)-dimensional non-Sasakian contact metric manifolds, we consider Legendre curves whose mean curvature vector fields are C-parallel or C-proper in the tangent or normal bundles. We obtain the curvature characterizations ... -
Mixed modulus of smoothness with Muckenhoupt weights and approximation by angle
(Taylor & Francis LTD, 2019)Mixed modulus of smoothness in weighted Lebesgue spaces with Muckenhoupt weights are investigated. Using mixed modulus of smoothness we obtain Potapov type direct and inverse estimates of angular trigonometric approximation ... -
Rotational submanifolds in Euclidean spaces
(World Scientific Publ CO PTE LTD, 2019)The rotational embedded submanifold was first studied by Kuiper as a submanifold in En+d The generalized Beltrami submanifolds and toroidal submanifold are the special examples of these kind of submanifolds. In this paper, ... -
Fixed-discs in rectangular metric spaces
