Intrinsic and Extrinsic Geometry of Kählerian Slant Submanifolds in Complex Space Forms

open access: yesMathematics
The study of complex space forms plays a central role in differential geometry, as these manifolds provide a natural framework for exploring geometric structures endowed with rich symmetries, extending both Riemannian and Kählerian geometries.

Ricci curvature of submanifolds in Kenmotsu space forms

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2002
In 1999, Chen established a sharp relationship between the Ricci curvature and the squared mean curvature for a submanifold in a Riemannian space form with arbitrary codimension.

Algebra of Complex Vectors and Applications in Electromagnetic Theory and Quantum Mechanics

open access: yesMathematics, 2015
A complex vector is a sum of a vector and a bivector and forms a natural extension of a vector. The complex vectors have certain special geometric properties and considered as algebraic entities. These represent rotations along with specified orientation

A study on hypersurface of complex space form

open access: yesActa et Commentationes Universitatis Tartuensis de Mathematica, 2013
We show that quasi-umbilical, generalized quasi-umbilical, super quasi-umbilical hypersurfaces of a complex space form are quasi-Einstein, mixed generalized quasi-Einstein and mixed super quasi-Einstein manifolds, respectively. We also prove that a Bochner at space of generalized complex space form is an Einstein manifold.

Linear differential equations with coefficients in Fock type space

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2011
In this paper we deal with complex differential equations of the form \begin{eqnarray*} f^{(k)}+a_{k-1}(z)f^{(k-1)}+\cdot\cdot\cdot+a_{1}(z)f^{'}+a_{0}(z)f=0 \end{eqnarray*} with the coefficients in Fock type space.

Understanding the city through its semiotic spatialities

open access: yesSign Systems Studies, 2011
The city is a complex sociocultural phenomenon where space and time are simultaneously parts of itself and parts of its conceptualisation. In the paper I draw out three general perspectives where the city is characterised by different spatialities and ...

Classification of Complex Fuzzy Numbers and Fuzzy Inner Products

open access: yesMathematics, 2020
The paper is concerned with complex fuzzy numbers and complex fuzzy inner product spaces. In the classical complex number set, a complex number can be expressed using the Cartesian form or polar form. Both expressions are needed because one expression is

An Immersion of an $n$-dimensional Real Space Form into an $n$-dimensional Complex Space Form

open access: yesTokyo Journal of Mathematics, 1986
Let \(M\) be an \(n\)-dimensional submanifold of an \(m\)-dimensional Riemannian manifold \(N\) and \(H\) be the mean curvature vector of \(M\). Let \(\zeta_ x\) be \(m-n\) mutually orthogonal unit normal vector fields of \(M\) such that \(H=| H|_{\zeta_ 1}\). The normal vector \(a(H)\) defined by \[ a(H)=(| H| /n)\sum^{m-n}_{x=2}Tr(A_ 1 A_ x)\zeta_ x \

Towards a Faddeev-AGS description of (d, p) reactions with heavy nuclei: Regularizing integrals with Coulomb functions.

open access: yesEPJ Web of Conferences, 2016
The repulsive Coulomb force poses severe challenges when describing (d, p) reactions for highly charged nuclei as a three-body problem. Casting Faddeev-AGS equations in a Coulomb basis avoids introducing screening of the Coulomb force.

Geometry of conformal vector fields

open access: yesArab Journal of Mathematical Sciences, 2017
It is well known that the Euclidean space (Rn,〈,〉), the n-sphere Sn(c) of constant curvature c and Euclidean complex space form (Cn,J,〈,〉) are examples of spaces admitting conformal vector fields and therefore conformal vector fields are used in ...
