The value of the work done by an isotropic vector force field along an isotropic curve
Dimitar Razpopov, Georgi Dzhelepov
In the present paper we consider a 3-dimensional differentiable manifold equipped with a Riemannian metric and an endomorphism , whose third power is the identity and $Q…
Two types of Lie Groups as 4-dimensional Riemannian manifolds with circulant structure
Iva Dokuzova, Dimitar Razpopov, Mancho Manev
A 4-dimensional Riemannian manifold equipped with an endomorphism of the tangent bundle, whose fourth power is the identity, is considered. The matrix of this structure in some bas…
A general semilocal convergence theorem for simultaneous methods for polynomial zeros and its applications to Ehrlich's and Dochev-Byrnev's methods
Petko D. Proinov
In this paper, we establish a general semilocal convergence theorem (with computationally verifiable initial conditions and error estimates) for iterative methods for simultaneous…
On a family of Weierstrass-type root-finding methods with accelerated convergence
Petko D. Proinov, Maria T. Vasileva
Kyurkchiev and Andreev (1985) constructed an infinite sequence of Weierstrass-type iterative methods for approximating all zeros of a polynomial simultaneously. The first member of…
General convergence theorems for iterative processes and applications to the Weierstrass root-finding method
Petko D. Proinov
In this paper, we prove some general convergence theorems for the Picard iteration in cone metric spaces over a solid vector space. As an application, we provide a detailed converg…
On the curvature properties of real time-like hypersurfaces of Kaehler manifolds with Norden metric
Mancho Manev, Marta Teofilova
A type of almost contact hypersurfaces with Norden metric of a Kaehler manifold with Norden metric is considered. The curvature tensor and the special sectional curvatures are char…
