Abstract: Rockafellar's proximal point algorithm is known to be not strongly convergent in general in an infinite-dimensional Hilbert space. Effort has thus been made to modify this algorithm so that strong convergence is guaranteed. In this paper we provide a strongly convergent modification of Rockafellar's proximal point algorithm in a uniformly convex Banach space which is not necessarily smooth.

Key Words and Phrases: Maximal monotone operator, proximal point algorithm, strong convergence, generalized projection, uniformly convex Banach space, zero point.
