Abstract We consider a nonlinear Robin problem driven by a nonhomogeneous differential operator which incorporates the p -Laplacian as special case. The reaction f (z, x) f (z, x) is a Carathéodory function which need not satisfy a global growth condition and is only assumed to be odd near zero. Using variational tools, we show that the problem has a whole sequence of distinct nodal (that is, sign-changing) solutions.
