Analogs of generalized resolvents and eigenfunction expansions of   relations generated by pair of differential operator expressions one of which   depends on spectral parameter in nonlinear manner
  For the relations generated by pair of differential operator expressions one of which depends on the spectral parameter in the Nevanlinna manner we construct analogs of the generalized resolvents which are integro-differential operators. The expansions in eigenfunctions of these relations are obtained.
