Shifting processes with cyclically exchangeable increments at random
  We propose a path transformation which applied to a cyclically exchangeable increment process conditions its minimum to belong to a given interval.   This path transformation is then applied to processes with start and end at zero. It is seen that, under simple conditions, the weak limit as epsilon tends to zero of the process conditioned on remaining above minus epsilon exists and has the law of the Vervaat transformation of the process.   We examine the consequences of this path transformation on processes with exchangeable increments, L\'evy bridges, and the Brownian bridge.
