Multiple positive solutions for a nonlocal problem involving critical exponent. <i>Electronic Journal of Differential Equations, 2017</i>(275), pp. 1-11.1072-6691https://hdl.handle.net/10877/16076This article concerns the nonlocal problem -(α - b ∫ℝ4|∇u|2 dx) ∆u = |u|2u + μƒ(x), in ℝ4, u ∈ D1,2(ℝ4), where α, b are positive constants, μ is a non-negative parameter, ƒ(x) ∈ L4/3(ℝ4) is a non-negative function. By using the variational method, the existence of multiple positive solutions are obtained.Text11 pages1 file (.pdf)enAttribution 4.0 InternationalMultiple positive solutionsNonlocal problemCritical exponentArticle
