Jackson type inequalities for differentiable functions in weighted orlicz spaces
(Amer Mathematical Soc, 2022)In the present work some Jackson Stechkin type direct theorems of trigonometric approximation are proved in Orlicz spaces with weights satisfying some Muckenhoupt Apcondition. To obtain a refined version of the Jackson ... -
On tzitzeica surfaces in euclidean 3-space mathbbE3
(Balıkesir Üniversitesi, 2021)In this study, we consider Tzitzeica surfaces (Tz-surface) in Euclidean 3-Space ... . We have been obtained Tzitzeica surfaces conditions of some surfaces. Finally, examples are given for these surfaces. -
Numerical solutions and synchronization of a variable-order fractional chaotic system
(Mehmet Yavuz, 2021)In the present paper, we implement a novel numerical method for solving differential equations with fractional variableorder in the Caputo sense to research the dynamics of a circulant Halvorsen system. Control laws are ... -
Existence and uniqueness results for a computer virus spreading model with atangana-baleanu derivative
(Manisa Celal Bayar Üniversitesi Fen Bilimleri Enstitüsü, 2021)A virus is programs that are often hidden inside a file that appears to be harmless and cause unexpected and unwanted events on the computer when the file is run. Viruses, unlike others, are software designed to maliciously ... -

Finite Blaschke products and the golden ratio
(Ankara Üniv. Fen Fakültesi, 2021)Geometric properties of finite Blaschke products have been intensively studied by many different aspects. In this paper, our aim is to study geometric properties of finite Blaschke products related to the golden ratio ... -
Solving a well-posed fractional initial value problem by a complex approach
(Springer Nature, 2021)Nonlinear fractional differential equations have been intensely studied using fixed point theorems on various different function spaces. Here we combine fixed point theory with complex analysis, considering spaces of ... -
Weighted variable exponent grand Lebesgue spaces and inequalities of approximation
(Hacettepe Univ, 2021)In this paper we discuss and investigate trigonometric approximation in weighted grand variable exponent Lebesgue spaces. We also prove the direct and inverse theorems in these spaces. -
Fixed discs in quasi-metric spaces
(House Book Science-Casa Cartii Stiinta, 2021)In this paper, we present some results of fixed disc and common fixed disc in quasi-metric spaces, under some very interesting contractions. Obtained results are supported by illustrative examples. -
Fixed-disc results on metric spaces
(Univ Nis, 2021)In this paper, we deal with the geometric properties of non-unique fixed points for self-mappings of a metric space (resp. an S-metric space). The fixed-disc (resp. fixed-circle) problem has been investigated in this ... -
Context Sensitive Links 1 of 1 Microencapsulation of basil essential oil: utilization of gum arabic/whey protein isolate/maltodextrin combinations for encapsulation efficiency and in vitro release
(Springer, 2021)Basil (Ocimum basilicum L.) essential oil (BEO) draws attention for its phenolic acid content which causes it to be used as a medicinal agent and food additive. However, its vulnerability to environmental and technological ... -
System response of an alcoholism model under the effect of immigration via non-singular kernel derivative
(Amer Inst Mathematical Sciences-AIMS, 2021)In this study, we aim to comprehensively investigate a drinking model connected to immigration in terms of Atangana-Baleanu derivative in Caputo type. To do this, we firstly extend the model describing drinking model by ... -
A note on killing calculus on Riemannian manifolds
(MDPI, 2021)In this article, it has been observed that a unit Killing vector field xi on an n-dimensional Riemannian manifold (M,g), influences its algebra of smooth functions C-infinity(M). For instance, if h is an eigenfunction of ... -
Relations between extrinsic and intrinsic invariants of statistical submanifolds in sasaki-like statistical manifolds
(MDPI, 2021)The Chen first inequality and a Chen inequality for the delta(2, 2)-invariant on statistical submanifolds of Sasaki-like statistical manifolds, under a curvature condition, are obtained. -
A key manipulation attack on some recent isogeny-based key agreement protocols
(Springer Singapore Pte Ltd, 2021)Recently, Daghigh et al. proposed some isogeny-based key agreement protocols in Bull. Iran. Math. Soc. 43 (2017), no. 4, 77-88. They claimed that their key exchange protocols based on supersingular isogenies provide the ... -
On the geometry of the crossed product of groups
(Korean Mathematical Soc, 2021)In this paper, firstly, we work on the presentation of the crossed product of groups of general types. After that we find the generating pictures (Second Homotopy Group) of this product by looking the relations from a ... -
A higher version of Zappa products for monoids
(Hacettepe Univ, 2021)For arbitrary monoids A and B, a presentation for the restricted wreath product of A by B that is known as the semi-direct product of A(circle plus B) by B has been widely studied. After that a presentation for the Zappa ... -
