We prove the existence and concentration of nodal solutions which concentrate around a k-dimensional sphere of R<sup>N</sup>, where (Formula presented.). The radius of such a sphere is related with the local minimum of a function which takes into account the potential V. Variational methods are used together with the penalization technique in order to overcome the lack of compactness.engconcentration on manifoldsnodal solutionsvariational methodsNodal solutions of an NLS equation concentrating on lower dimensional spheresArtigo10.1186/s13661-015-0411-8Acesso aberto2-s2.0-849422347332-s2.0-84942234733.pdf
