de Figueiredo, Djairo G. Semilinear elliptic equations at resonance: higher eigenvalues and unbounded nonlinearities. (English) Zbl 0599.47096 Recent advances in differential equations, Meet. Miramare (Trieste)/Italy 1978, 89-99 (1981). [For the entire collection see Zbl 0588.00019.] Equations of the type \[ Au+Bu=h \] are considered, where A is some unbounded linear operator in a Hilbert space H and B is some nonlinear operator.
