• monotonicity

We continue the study of the existence of square iterative roots of multifunctions with exactly one set-value point, reported by the third and fourth authors in [7]. First we present nonexistence results in some cases not considered there. Then we give a full description of square roots of strictly monotone, upper semicontinuous multifunctions. The last extends the construction presented by M. KUCZMA [9].
