Abstract
In order to obtain some existence results for certain generalized eigenvalue problems nd to study certain parametrized boundary value problems for second order differential nclusions, we generalize some fixed point theorems for completely continuous (single-valued) aps to the multivalued case. We illustrate our results with some examples.
