In this paper, we discuss the existence and uniqueness of points of coincidence and common fixed points for a pair of graph preserving mappings in parametric $N_b$-metric spaces. As some consequences of this study, we obtain several important results in parametric $b$-metric spaces, parametric $S$-metric spaces and parametric $A$-metric spaces. Finally, we provide some illustrative examples to ...

We consider the single-machine preemptive Pareto-scheduling problem with two competing agents A and B, where agent wants to minimize number of its jobs (the A-jobs) that is tardy, while B total late work B-jobs). provide an $$O(nn_{A}\log n_{A}+n_B\log n_B)$$ -time algorithm generates all Pareto-optimal points, $$n_A$$ A-jobs, $$n_B$$ B-jobs, $$n=n_A+n_B$$ .

In this paper, some topological properties are discussed and results on completeness, totally boundedness, compactness parametric S-metric spaces developed.

We delineate the quark-hadron continuity by constructing QCD equations of state for neutron star dynamics, covering wide range charge chemical potential ($\mu_Q$) and temperatures ($T$). Based on nuclear-2SC scenario, we match nuclear two-flavor color-superconducting (2SC) quark matter, where matching baryon density is $n_B\simeq 1.5n_0$ ($n_0\simeq 0.16\, {\rm fm^{-3}}$: saturation density). T...

We report the results of computation order $(k_{\rm F}a_0)^2$ correction, where $k_{\rm F}=3\pi^2\rho$ is Fermi wave vector and $a_0$ $s$-wave scattering length repulsive interaction, to ground-state energy a mixture oppositely polarized $N_a$ spin $1/2$ fermions $a$ masses $m_a$ $N_b$ $b$ $m_b$ ($\rho=N/V$, $N=N_a+N_b$). It shown that paper \cite{FraPil} in which same correction has been compu...

A method is presented for meshing 3D CAD surfaces in parametric space using an advancing front approach and a metric map to govern the size and shape of the triangles in the parametric space. The creation of the metric map will be discussed. The advancing front mesher generates triangles based on the metric map, stretching them in order to capture the change in parameterization of the surface. ...

This paper introduces a parameterization-based approach for anisotropic surface meshing. Given an input surface equipped with an arbitrary Riemannian metric, this method generates a metric-adapted mesh with user-specified number of vertices. In the proposed method, the edge length of the input surface is directly adjusted according to the given Riemannian metric at first. Then the adjusted surf...
