G3'te DeltaIIxi=lambdaixi şartını sağlayan küresel çarpım yüzeyleri
(Balıkesir Üniversitesi, 2021)n-boyutlu bağlantılı bir manifolddan m-boyutlu Öklid uzayına tanımlı bir izometrik daldırma için, M manifoldunun yer vektörü Laplas operatörünün sabit olmayan öz fonksiyonlarının sonlu bir toplamı olarak ayrışabiliyorsa, ... -
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 ... -
Approximation by matrix transforms in generalized grand Lebesgue spaces with variable exponent
(Taylor & Francis Ltd, 2021)The approximation properties of the matrix transforms, constructed via lower triangular matrices, satisfying some additional conditions, in the generalized grand Lebesgue spaces with variable exponent are studied and the ... -
Direct and inverse theorems in variable exponent smirnov classes
(Inst Mathematics & Mechanics, 2021)Let G be a simple connected bounded domain in the complex plane C. Imposing some additional conditions on the variable exponent p (.), we prove direct and inverse theorems of approximation theory in the variable exponent ... -
Sharp inequalities for anti-invariant Riemannian submersions from Sasakian space forms
(Elsevier, 2021)We obtain sharp inequalities involving the Ricci curvature and the scalar curvature for anti-invariant Riemannian submersions from Sasakian space forms onto Riemannian manifolds. -
Asymptotically good towers of function fields with small p-rank
(Academic Press Inc Elsevier Science, 2021)Over any quadratic finite field we construct function fields of large genus that have simultaneously many rational places, small p-rank, and many automorphisms. -
Forecasting of the Istanbul Stock Exchange (ISE) return with a golden ratio model in the epidemic of Covid-19
(Ministry Communications & High Technologies Republic Azerbai, 2021)A novel coronavirus called COVID-19 has spread rapidly all over the world in the recent days. This virus, which has become a global problem, has deeply affected the stock markets. This paper aims to present a new model ... -
Discontinuous convex contractions and their applications in neural networks
(Springer Heidelberg, 2021)In this paper, we show that the class of convex contractions of order m ∈ N is strong enough to generate a fixed point but do not force the mapping to be continuous at the fixed point. As a by-product, we provide a new ... -
A fractional model of cancer-immune system with Caputo and Caputo-Fabrizio derivatives
(Springer Heidelberg, 2021)Recently, it is important to try to understand diseases with large mortality rates worldwide, such as infectious disease and cancer. For this reason, mathematical modeling can be used to comment on diseases that adversely ...
