摘要

This paper studies an anisotropic singular problem driven by \((\overset{\rightarrow }{p}(\cdot ),\overset{\rightarrow }{q}(\cdot ))\) ( p ( · ) , q ( · ) ) -Laplacian operator with the variable strong-singularity and the variable Hardy-type potential. As the main machinery, the Ekeland’s variational principle and constrained minimization are applied to obtain the existence and uniqueness of a positive solution. An application is provided to illustrate the main result.
