Spectral radius and Hamiltonian properties of graphs, IIJun 28 2016Mar 18 2019In this paper, we first present spectral conditions for the existence of $C_{n-1}$ in graphs (2-connected graphs) of order $n$, which are motivated by a conjecture of Erd\H{o}s. Then we prove spectral conditions for the existence of Hamilton cycles in ... More
Spectral analogues of Erdős' and Moon-Moser's theorems on Hamilton cyclesApr 14 2015Feb 27 2016In 1962, Erd\H{o}s gave a sufficient condition for Hamilton cycles in terms of the vertex number, edge number, and minimum degree of graphs which generalized Ore's theorem. One year later, Moon and Moser gave an analogous result for Hamilton cycles in ... More
New Approach on the General Shape Equation of Axisymmetric VesiclesJan 10 1999The general Helfrich shape equation determined by minimizing the curvature free energy describes the equilibrium shapes of the axisymmetric lipid bilayer vesicles in different conditions. It is a non-linear differential equation with variable coefficients. ... More
