Positive Periodic Solutions of Coupled Singular Rayleigh Systems

Positive periodic solutions for a $\phi$-Laplacian generalized Rayleigh equation with a singularity

“…At the same time, Rayleigh equations with a singularity were also explored by authors [14,15,16,17,18,19,20,21]. For example, Lu et al [18] discussed p-Laplacian Rayleigh equations with a singularity in 2016 as follows:…”
