    The author obtains some interesting set-valued variants of \textit{N. M. Gulevich's} fixed point theorems for nonexpansive maps [J. Sov. Math. 26, 1607-1611 (1984; Zbl 0538.47032)], wherein he adopts ``more general boundary conditions such as the weakly inwardness or the Leray-Schauder condition than the Rothe condition in Gulevich's theorem [op. cit.]''.
