In this article, we study the following fractional elliptic equation with critical growth and singular nonlinearity: (Equation presented) where Ω is a bounded domain in ℝn with smooth boundary ∂Ω, n > 2s, s ∈ (0, 1), λ > 0, q > 0 and 2∗s = 2n/n-2s. We use variational methods to show the existence and multiplicity of positive solutions with respect to the parameter λ. © 2017 Walter de Gruyter GmbH, Berlin/Boston.
