A general existence principle for fixed point theorems in one parameter case of soft Da-metric space

, 2022
In this article we define orbit and related terminologies for soft sets. We prove some fixed point results for soft \(D_{a}\)- metric space in a specific orbital case and extending various general principles for fixed point theorems in \(D\)-metric space

Estimating the weight of metric minimum spanning trees in sublinear time [PDF]

, 2008
In this paper we present a sublinear-time $(1+\varepsilon)$-approximation randomized algorithm to estimate the weight of the minimum spanning tree of an $n$-point metric space. The running time of the algorithm is $\widetilde{\mathcal{O}}(n/\varepsilon^{\

Reaction Networks and the Metric Structure of Chemical Space(s) [PDF]

, 2019
In this paper, we develop a formal definition of chemical space as a discrete metric space of molecules and analyze its properties. To this end, we utilize the shortest path metric on reaction networks to define a distance function between molecules of ...

Metric properties of outer space

We define metrics on Culler-Vogtmann space, which are an analogue of the Teichmuller metric and are constructed using stretching factors. In fact the metrics we study are related, one being a symmetrised version of the other.

Solar Type III Radio Burst Identification Using Few-Shot Object Detection

Universe
Solar radio bursts at very low frequencies are key phenomena in the Sun–Earth space environment, providing crucial diagnostics of the acceleration and propagation of solar wind, coronal mass ejection (CME), and non-thermal energetic particles and serving

Fixed point theorems of contractive mappings on soft parametric metric space

The purpose of this study was to introduce soft topology generated by soft parametric metric space and prove Banach's fixed point theorem as an extension of soft complete parametric metric space.
