摘要

We study the conditional entropy of topological dynamical systems using a family of metrics induced by probability bi-sequences. We present a Brin-Katok formula by replacing the mean metric by a family of metrics induced by a probability bi-sequence. We also establish the Katok’s entropy formula for conditional entropy for ergodic measures in the case of the new family of metrics.
