We obtain some fixed point theorems with error estimates for multivalued mappings satisfying a new --contractive type condition. Our theorems generalize many existing fixed point theorems, including some fixed point theorems proved for -contractive type conditions. → implies ( ) ≤ lim inf ( ). Throughout this paper denotes an interval on R + containing 0, that is, an interval of the form [0, ], [0, ), or [0, ∞) and ( ) denotes the polynomial ( ) = 1 + + ⋅ ⋅ ⋅ + −1 . We use the abbreviation for the th iterate of a function : → .
