Abstract:

Let $C$ be a bounded closed convex subset of a Banach space $X$. It is shown that, in the category sense, almost all $1$-set-contractions $f:C \to C$ are condensing. To know how the condensing mappings are scattered in the set ${\Sigma _1}(C)$ of $1$-set-contractions it is proved that the set of noncondensing mappings is dense in ${\Sigma _1}(C)$.
