Abstract:
In a recent paper [S. Ghosh, Phys. Rev. E 103, 023205 (2021)2470-004510.1103/PhysRevE.103.023205], the transport properties of the two-dimensional weakly nonlinear quasilongitudinal dust lattice mode were investigated in a highly viscous, strongly coupled, and weakly ionized plasma. Based on the computational results, the author predicted strong viscosity induced Shilnikov homoclinic chaos. In this Comment, it is shown that the dynamical system presented in the paper is inconsistent and incorrect because of an error in the expression of ε. As a result, period-2, period-4, chaotic and homoclinic chaotic phenomena do not exist, which were observed in the paper.

Stability of Equilibrium Configuration
A stable equilibrium occurs when a system tends to return to its original position when given a small displacement, and the potential energy is at its minimum. An example of a stable equilibrium is when a cantilever beam is fixed at one end and a weight is attached to the other end. If the weight...
