Convergence of a sequence of sets in a Hadamard space and the shrinking projection method for a real Hilbert ball
Summary: We propose a new concept of set convergence in a Hadamard space and obtain its equivalent condition by using the notion of metric projections. Applying this result, we also prove a convergence theorem for an iterative scheme by the shrinking projection method in a real Hilbert ball.
