Best constant in critical Sobolev inequalities of second-order in the presence of symmetries

Let (M, g) be a smooth compact Riemannian manifold. We first give the value of the best first constant for the critical embedding H2 (M) {right arrow, hooked} L2{music sharp sign} (M) for second-order Sobolev spaces of functions invariant by some subgroup of the isometry group of (M, g). We also pro...
