    0 references
    The paper is a survey, containing the following main topics: extensions of the Banach contraction principle for multimaps, the topological structure of fixed point sets (including conditions under which they are absolute retracts and lower estimates of their topological dimension), topological essentiality of multimaps, applications to the existence of almost periodic solutions for differential inclusions.NEWLINENEWLINEFor the entire collection see [Zbl 0970.00036].
