Pointwise density topology [PDF]

open access: yes, 2015
The paper presents a new type of density topology on the real line generated by the pointwise convergence, similarly to the classical density topology which is generated by the convergence in measure.

Tubular Surface Having Pointwise 1-type Gauss Map in Euclidean 4-Space

open access: yesInternational Electronic Journal of Geometry, 2019
Summary: In this paper, we deal with a tubular surface in Euclidean 4-space \(\mathbb E^4\). We study this surface with respect to its Gauss map. We show that there is not any tubular surface having harmonic Gauss map and we give the complete classification of tubular surface having pointwise 1-type Gauss map in Euclidean 4-space \(\mathbb E^4\).

General rotational surfaces in Euclidean space $\mathbb{E}^4$ with pointwise 1-type Gauss map [PDF]

open access: yes, 2012
In this paper, we study general rotational surfaces in $\mathbb E^4$ with pointwise 1-type Gauss map. We consider general rotational surfaces in $\mathbb E^4$ whose meridian curves lie in two-dimensional planes. We firstly obtain all general rotational

SURFACES OF REVOLUTION WITH POINTWISE 1-TYPE GAUSS MAP IN MINKOWSKI 3-SPACE

open access: yesTaiwanese Journal of Mathematics, 2009
We study the rational surfaces of revolution in Minkowski 3-space and characterize them with pointwise 1-type Gauss map. In this article, we give a complete classification of rational surfaces of revolution in Minkowski 3-space with pointwise 1-type Gauss map and provide new examples of cones in Minkowski 3-space.

Flat surfaces in the Euclidean space E3 with pointwise 1-type Gauss map [PDF]

open access: yes, 2010
In this article we prove that a at nonplanar surface in the Eu- clidean space E3 with pointwise 1-type Gauss map of the second kind is either a right circular cone or a cylinder such that the curvature of the base curve satises a specic dierential ...

Unified framework for the separation property in binary phase-segregation processes with singular entropy densities

open access: yesEuropean Journal of Applied Mathematics
This paper investigates the separation property in binary phase-segregation processes modelled by Cahn-Hilliard type equations with constant mobility, singular entropy densities and different particle interactions.

Maximum norm a posteriori error estimation for parabolic problems using elliptic reconstructions [PDF]

open access: yes, 2013
A semilinear second-order parabolic equation is considered in a regular and a singularly perturbed regime. For this equation, we give computable a posteriori error estimates in the maximum norm.

A Note on Spherical Product Surface with L_1-Pointwise 1-Type Gauss Map

open access: yes, 2021
In this study, we deal with the spherical product surface whose Gauss map G satisfies the equality L_1G=f(G+C) where L_1 is the Cheng-Yau operator in Galilean 3-space G_3 . We obtain the necessary and sufficient conditions for spherical product surface to have L_1-pointwise 1-type Gauss map in G_3.
