Positive solutions for anisotropic discrete boundary-value problems

open access: yesElectronic Journal of Differential Equations, 2013
Using mountain pass arguments and the Karsuh-Kuhn-Tucker Theorem, we prove the existence of at least two positive solution for anisotropic discrete Dirichlet boundary-value problems. Our results generalized and improve those in [16].
