The wandering subspace problem for an analytic (norm-increasing) m-isometry T on a Hilbert space H asks whether every T-invariant subspace of H can be generated by a wandering subspace. An affirmative solution to this problem for m = 1 is ascribed to Beurling-Lax-Halmos, while that for m = 2 is due to Richter. In this talk, we discuss present status of this problem including some partial solutions in case m > 2.
