    A complete metric space without non-trivial separable Lipschitz retracts

  • Original language description

    We construct a complete metric space M of cardinality continuum such that every non-singleton closed separable subset of M fails to be a Lipschitz retract of M. This provides a metric analogue to the various classical and recent examples of Banach spaces failing to have linearly complemented subspaces of prescribed smaller density character.
