English translation: Bulletin of the South Ural State University,
Series: Mathematical Modelling, Programming and Computer Software, 2016, 9,
20-31, 2014 The paper discusses the conditions for the existence of fixed points of multivalued mappings that are not based on the linear structure of the set. The descriptions for the sets of fixed points for mappings with closed graph in compact Hausdorff spaces and in metrizable spaces, as well as for continuous functions in spaces with convergence (Frechet ...
