System analysis of HIV infection model with CD4(+)T under non-singular kernel derivative
(Walter De Gruyter GMBH, 2020)Infectious diseases have caused the death of many people throughout the world for centuries. For this purpose, many researchers have investigated these diseases for establishing new treatment and protective measures. The ... -
Bilateral-type solutions to the fixed-circle problem with rectified linear units application
(Scientific Technical Research Council Turkey-Tubitak, 2020)In this paper, we prove new fixed-circle (resp. fixed-disc) results using the bilateral type contractions on a metric space. To do this, we modify some known contractive conditions called the Jaggi-type bilateral contraction ... -
A new solution to the discontinuity problem on metric spaces
(Scientific Technical Research Council Turkey-Tubitak, 2020)We study on the Rhoades' question concerning the discontinuity problem at fixed point for a self-mapping T of a metric space. We obtain a new solution to this question. Our result generalizes some recent theorems existing ... -
Some generalized fixed-point theorems on complex valued s-metric spaces
(Tsing Hua Univ, 2020)In this paper, we define new contractive conditions on a complex valued S-metric space. These contractive conditions generalize the classical Rhoades' contractive condition, Nemytskii-Edelstein contractive condition and ... -
An integral formula for bi-slant submanifolds in complex space forms
(Hacettepe Univ, 2020)The present paper deals with bi-slant submanifolds in complex space forms. We obtain an integral formula of Simons' type for bi-slant submanifolds of a complex space form with positive constant holomorphic sectional ... -
Fractional order mixed difference operator and its applications in angular approximation
(Hacettepe Univ, 2020)Lebesgue spaces are considered with Muckenhoupt weights. Fractional order mixed difference operator is investigated to obtain mixed fractional modulus of smoothness in these spaces. Using this modulus of smoothness we give ... -
Commutator subgroups of generalized Hecke and extended generalized Hecke groups,II
(Scientific Technical Research Council Turkey-Tubitak, 2020)Let p(1), ..., p(n) be integers where n >= 2 and each p(i) >= 2. Let also H(p(1), ..., p(n)) be the generalized Hecke group associated to all p(i) >= 2. In this paper, we study the commutator subgroups H'(p(1), ..., p(n)) ... -
The new derivation for wreath products of monoids
(Univ Nis, 2020)We first define a new consequence of the (restricted) wreath product for arbitrary two monoids. After that we give a generating and relator set for this new wreath product. Then we denote some finite and infinite applications ... -
An approach to pre-separation axioms in neutrosophic soft topological spaces
(Ankara Univ, 2020)In this study, we introduce the concept of neutrosophic soft preopen (neutrosophic soft pre-closed) sets and pre-separation axioms in neutrosophic soft topological spaces. In particular, the relationship between these ... -
On the geometry of fixed points for self-mappings on s-metric spaces
(Ankara Univ, 2020)In this paper, we focus on some geometric properties related to the set Fix(T), the set of all fixed points of a mapping T : X -> X, on an S-metric space (X, S). For this purpose, we present the notions of an S-Pata type ... -

Highly nonlinear (Vectorial) Boolean functions that are symmetric under some permutations
(Amer Inst Mathematical Sciences-AIMS, 2020)We first give a brief survey of the results on highly nonlinear single-output Boolean functions and bijective S-boxes that are symmetric under some permutations. After that, we perform a heuristic search for the symmetric ... -
On pseudo-hermitian biharmonic slant curves in sasakian space forms endowed with the tanaka-webster connection
(Springer Singapore Pte Ltd, 2020)In this paper, we consider pseudo-Hermitian biharmonic slant curves in (2n + 1)-dimensional Sasakian manifolds endowed with the Tanaka-Webster connection. We investigate pseudo-Hermitian curvatures of slant curves in six ... -
Approximation by p(·)-Faber polynomials in the variable Smirnov classes

Reduced order optimal control of the convective FitzHugh-Nagumo equations
(Pergamon-Elsevier Science Ltd, 2020)In this paper, we compare three model order reduction methods: the proper orthogonal decomposition (POD), discrete empirical interpolation method (DEIM) and dynamic mode decomposition (DMD) for the optimal control of the ... -
Comparing the new fractional derivative operators involving exponential and Mittag-leffler kernel
(Amer Inst Mathematical Sciences-AIMS, 2020)In this manuscript, we have proposed a comparison based on newly defined fractional derivative operators which are called as Caputo-Fabrizio (CF) and Atangana-Baleanu (AB). In 2015, Caputo and Fabrizio established a new ... -
