Abstract: The following result is shown. If is a lipschitzian pseudo-contractive map of a compact convex subset
of a Hilbert space into itself and
is any point in
, then a certain mean value sequence defined by
converges strongly to a fixed point of
, where
and
are sequences of positive numbers that satisfy some conditions.
