In this note we prove that if a differentiable function oscillates between y and on the boundary of the unit ball then there exists a point in the interior of the ball in which the differential of the function has norm equal or less than . This kind of approximate Rolle's theorem is interesting beca

Various random fixed point theorems for different classes of 1-set-contractive random operator are proved. The class of 1-set-contractive random operators includes condensing and nonexpansive random operators. It also includes semicontractive type random operators and locally almost nonexpansive ran
