Comparing the Morse index and the first Betti number of minimal hypersurfaces [PDF]

, 2018
By extending and generalizing previous work by Ros and Savo, we describe a method to show that in certain positively curved ambient manifolds the Morse index of every closed minimal hypersurface is bounded from below by a linear function of its first ...

\tau*-generalized semi continuous functions in topological spaces

International Journal of Mathematical Analysis, 2013
In this paper, we introduce new class of functions called τ ∗ -Generalized Semi Continuous functions in topological spaces and study some of its properties and its relationship with some existing functions.

Composition and multiplication operators between Orlicz function spaces

Journal of Inequalities and Applications, 2016
Composition operators and multiplication operators between two Orlicz function spaces are investigated. First, necessary and sufficient conditions for their continuity are presented in several forms.

Fast S-Parameter TAN Model of n-Port Lumped Structures

IEEE Access, 2019
This paper deals with the fast S-parameter modeling of multi-port lumped structures. The developed model is based on unfamiliar formalism using the tensorial analysis of networks (TAN).

Contra generalized fuzzy precontinuous functions in fuzzy topological spaces

Journal of Physics: Conference Series, 2018
The concept of generalized preclosed (gp-closed) subsets and generalized preopen (gp-open) functions in topology were studied and some of their characterizations have been introduced. The aim of this paper is to introduce a new class of functions called fuzzy contra generalized precontinuous functions using generalized fuzzy preopen (gp-fuzzy open ...

On Asymmetric Distances

Analysis and Geometry in Metric Spaces, 2013
In this paper we discuss asymmetric length structures and asymmetric metric spaces. A length structure induces a (semi)distance function; by using the total variation formula, a (semi)distance function induces a length.

Computing CMB Anisotropy in Compact Hyperbolic Spaces [PDF]

, 1998
The measurements of CMB anisotropy have opened up a window for probing the global topology of the universe on length scales comparable to and beyond the Hubble radius.
