On the existence and multiplicity of topologically twisting incompressible $H$-harmonic maps and a structural H-condition
In this paper we address questions on the existence and multiplicity of solutions to the nonlinear elliptic system in divergence formHere H = H(r,s) > 0 is a weight function of class C 2 with H s = ∂ H/∂ s and (r,s) = (|x|,|u| 2 ) , Ω ⊂ …
