Abstract
The Banach ultrapower construction is applied in fixed point theory for multivalued mappings. We introduce
the notion of ultra-asymptotic centers and use it to remove the separability assumption from the results
of Domínguez Benavides, Lorenzo Ramírez (2004) and Dhompongsa, Kaewcharoen, Kaewkhao (2006).
