Common fixed point results on complex-valued s-metric spaces
(Univ Maragheh, 2020)Banach's contraction principle has been improved and extensively studied on several generalized metric spaces. Recently, complex-valued S-metric spaces have been introduced and studied for this purpose. In this paper, we ... -
New results on discontinuity at fixed point
(Springer Basel AG, 2020)We obtain a Meir-Keeler type fixed-point theorem which gives a new solution to the Rhoades' problem on the existence of contractive mappings that admit discontinuity at the fixed point. Meir-Keeler type solutions of the ... -
Novel analysis of the fractional glucose-insulin regulatory system with non-singular kernel derivative
(Springer Heidelberg, 2020)Diabetes mellitus, at the forefront of the diseases of our age, is a type of disease that plays a leading role in the formation of many deadly diseases and is very common all over the world. In this work, based on the ... -
Constrained optimal control of a fractionally damped elastic beam
(Walter De Gruyter GMBH, 2020)This work presents the constrained optimal control of a fractionally damped elastic beam in which the damping characteristic is described with the Caputo fractional derivative of order 1/2. To achieve the optimal control ... -
Dynamical analysis of fractional order model for computer virus propagation with kill signals
(Walter De Gruyter GMBH, 2020)The kill signals are alert about possible viruses that infect computer network to decrease the danger of virus propagation. In this work, we focus on a fractional-order SEIR-KS model in the sense of Caputo derivative to ... -
Power and free normal subgroups of generalized Hecke groups
(World Scientific Publ Co Pte Ltd, 2020)Let p and q be integers such that 2 <= p <= q, p + q > 4 and let H-p,H- q be generalized Hecke group associated to p and q. Generalized Hecke group H-p,H- q is generated by X(z) = -(z - lambda(p))(-1) and Y(z) = -(z + ... -
Complex conformable Rolle's and mean value theorems
(Springer Heidelberg, 2020)In this paper, we present the complex Rolle's and Mean Value Theorems for alpha-holomorphic functions and give some related results and applications of these theorems. -
Belyi's theorems in positive characteristic
(World Scientific Publ Co Pte Lt, 2020)There are two types of Belyi's Theorems for curves defined over finite fields of characteristic p, namely the Wild and the Tame p-Belyi Theorems. In this paper, we discuss them in the language of function fields. In ... -
Some algebraic structures on the generalization general products of monoids and semigroups
(Springer Heidelberg, 2020)For arbitrary monoidsAandB, in Cevik et al. (Hacet J Math Stat 2019:1-11, 2019), it has been recently defined an extended version of the general product under the name ofa higher version of Zappa products for monoids(orgeneralized ... -
Geometric properties of discontinuous fixed point set of (epsilon-delta contractions and applications to neural networks)
(Springer Basel AG, 2020)In this paper, we prove some fixed point theorems under a convex combination of generalized ( − δ) type rational contractions in which the fixed point may or may not be a point of discontinuity. As a by-product we explore ... -
Pata zamfirescu type fixed-disc results with a proximal application
(Malaysian Mathematical Sciences Soc, 2020)This paper concerns with the geometric study of fixed points of a self-mapping on a metric space. We establish new generalized contractive conditions which ensure that a self-mapping has a fixed disc or a fixed circle. We ... -
Almost η-ricci and almost η-yamabe solitons with torse-forming potential vector field
(Natl Inquiry Services Centre Pty Ltd, 2020)We provide properties of almost eta-Ricci and almost eta-Yamabe solitons on submanifolds isometrically immersed into a Riemannian manifold ((M) over tilde, (g) over tilde) whose potential vector field is the tangential ... -
A quest of G-continuity in neutrosophic spaces
(Wiley, 2020)Continuity, in particular sequential continuity, is an important subject of investigation not only in topology but also in some other branches of mathematics. Connor and Grosse-Erdmann remodelled its definition for real ... -
Some fixed-circle theorems on metric spaces
(Malaysian Mathematical Sciences Soc, 2019)The fixed-point theory and its applications to various areas of science are well known. In this paper, we present some existence and uniqueness theorems for fixed circles of self-mappings on metric spaces with geometric ... -
On cosymplectic-like statistical submersions
(Springer Basel AG, 2019)We study cosymplectic-like statistical submersions. It is shown that for a cosymplectic-like statistical submersion, the base space is a Kahler-like statistical manifold and each fiber is a cosymplectic-like statistical ... -
New fixed-point theorems on an S-metric space via simulation functions
(MDPI, 2019)In this paper, we prove new fixed-point theorems using the set of simulation functions on an S-metric space with some illustrative examples. Our results are stronger than some known fixed-point results. Furthermore, we ... -
Direct theorems of trigonometric approximation for variable exponent Lebesgue spaces
(Union Matematica Argentina, 2019)Jackson type direct theorems are considered in variable exponent Lebesgue spaces L-p(x) with exponent p(x) satisfying 1 <= ess inf(x is an element of[0,2 pi]) p(x), ess sup(x is an element of[0,2 pi]) p(x) < infinity, and ... -
C-parallel and c-proper slant curves of S-manifolds
(Univ Nis, 2019)In the present paper, we define and study C-parallel and C-proper slant curves of S-manifolds. We prove that a slant curve gamma in an S-manifold of order r >= 3, under certain conditions, is C-parallel or C-parallel in ... -
Complete rewriting system and growth series for extended generalized hecke groups

Chen inequalities for statistical submanifolds of Kahler-Like statistical manifolds
(MDPI, 2019)We consider Kahler-like statistical manifolds, whose curvature tensor field satisfies a natural condition. For their statistical submanifolds, we prove a Chen first inequality and a Chen inequality for the invariant delta(2,2).
