Open Extension Topology

open access: yesPracì Mìžnarodnogo Geometričnogo Centru, 2015
The paper contains the results which describe the properties of such general topological construction as open extension topology. In particular, we prove that this topology is not transitive. We find the base of the least cardinality for the topology and

D7-Brane Moduli vs. F-Theory Cycles in Elliptically Fibred Threefolds

open access: yes, 2009
We study the space of geometric and open string moduli of type IIB compactifications from the perspective of complex structure deformations of F-theory.

On the solitons of the Chern-Simons-Higgs model [PDF]

open access: yes, 1998
Several issues concerning the self-dual solutions of the Chern-Simons-Higgs model are addressed. The topology of the configuration space of the model is analysed when the space manifold is either the plane or an infinite cylinder.

Topology Based Object Tracking [PDF]

open access: yesMathematical and Computational Applications, 2019
A model for tracking objects whose topological properties change over time is proposed. Such changes include the splitting of an object into multiple objects or the merging of multiple objects into a single object. The proposed model employs a novel formulation of the tracking problem in terms of homology theory whereby 0-dimensional homology classes ...

Analysis on the impact of router alias resolution

open access: yesTongxin xuebao, 2012
Router alias resolution is one of hard problems and important steps for router level Internet topology measurement based on traceroute mechanism,and the topology characteristic of the generated router level topology graph has close relationship with the ...

Higher spectral flow and an entire bivariant JLO cocycle

open access: yes, 2012
Given a smooth fibration of closed manifolds and a family of generalised Dirac operators along the fibers, we define an associated bivariant JLO cocycle. We then prove that, for any $\ell \geq 0$, our bivariant JLO cocycle is entire when we endow smoooth

On the Transmission-Based Graph Topological Indices [PDF]

open access: yesKragujevac Journal of Mathematics, 2020
The distance $d(u,v)$ between the vertices $u$ and $v$ of a connected graph $G$ is defined as the number of edges in a minimal path connecting them. The \emph{transmission} of a vertex $v$ of $G$ is defined by $σ(v)=\sum\limits_{u\in V(G)}{d(v,u)}$. In this article we aim to define some transmission-based topological indices.

Some Results on Soft Multi Topology

open access: yesSakarya Üniversitesi Fen Bilimleri Enstitüsü Dergisi, 2013
In this article, at first we recall the concept of soft multiset. Then some results which we obtained on soft multisets were given. Moreover, in this paper, the notion of soft multi topology was introduced and some results on soft multi topology and the ...

Topological, or Non-topological? A Deep Learning Based Prediction

open access: yes, 2023
Prediction and discovery of new materials with desired properties are at the forefront of quantum science and technology research. A major bottleneck in this field is the computational resources and time complexity related to finding new materials from ab initio calculations.

Topology optimization for elastic base under rectangular plate subjected to moving load

open access: yesArchives of Control Sciences, 2015
Distribution optimization of elastic material under elastic isotropic rectangular thin plate subjected to concentrated moving load is investigated in the present paper. The aim of optimization is to damp its vibrations in finite (fixed) time.
