El Khalil, Abdelouahed; Alaoui, My Driss Morchid; Touzani, Abdelfattah On the \(p\)-biharmonic operator with critical Sobolev exponent and nonlinear Steklov boundary condition. (English) Zbl 1390.35216 Int. J. Anal. 2014, Article ID 498386, 8 p. (2014). Summary: We show that this operator possesses at least one nondecreasing sequence of positive eigenvalues. A direct characterization of the principal eigenvalue (the first one) is given that we apply to study the spectrum of the \(p\)-biharmonic operator with a critical Sobolev exponent and the nonlinear Steklov boundary conditions using variational arguments and trace critical Sobolev embedding.
