Generalized Optimality Criteria Method for Topology Optimization

open access: yesApplied Sciences, 2021
In this article, a generalized optimality criteria method is proposed for topology optimization with arbitrary objective function and multiple inequality constraints. This algorithm uses sensitivity information to update both the Lagrange multipliers and

A uniform approach to normality for topological spaces

open access: yesApplied General Topology, 2016
$(\lambda, \mu)$-regularity and $(\lambda, \mu)$-normality are defined for generalized topological spaces. Several variants of normality existing in the literature turn out to be particular cases of $(\lambda, \mu)$-normality. Uryshon's lemma and Titze's

Some Properties of Generalized Topologies in GTSs

open access: yesCommunications in Advanced Mathematical Sciences, 2020
In this article, we introduce one new generalized topology and investigate its properties in a generalized topological space. Also, we give various properties of some generalized topologies defined in a generalized topological space.

Generality of topological inflation [PDF]

open access: yesClassical and Quantum Gravity, 2003
Many authors claimed that a large initial inhomogeneity prevents the onset of inflation and therefore inflation takes place only if the scalar field is homogeneous or appropriately chosen over the horizon scale. We show that those arguments do not apply to topological inflation.

Generalized open sets of Minkowski space [PDF]

open access: yesMathematica Moravica, 2015
We consider the Euclidean topology and s-topology on n-dimensional Minkowski space and investigate the interior and closure of the space cone and perforated space cone with respect to these topologies.

New generalized closure operators induced by local functions via ideals [PDF]

open access: yesJournal of Mahani Mathematical Research
This work aims to introduce and examine four new operators based on the topological structure “ideal” and the notion of “generalized” generating two generalized ideal topological spaces.

Topological gyrogroups: Generalization of topological groups

open access: yesTopology and its Applications, 2017
The author studies topological left automorphic left Bol loops. In the terminology of \textit{A. A. Ungar} [Analytic hyperbolic geometry and Albert Einstein's special theory of relativity. Hackensack, NJ: World Scientific (2008; Zbl 1147.83004)] left automorphic left Bol loops are called gyrogroups.

Continuous generalized metric spaces

open access: yes四川大学学报. 自然科学版, 2020
Continuous generalized metric spaces are introduced and investigated in this paper. It is shown that for such spaces, the generalized Scott topology is equal to c-Scott topology, and that a non-expansive map between such spaces is Yoneda continuous if ...
