摘要：A multiplicative subshift X derived from the subshift is invariant under multiplicative integer action, which is closely related to the level set of multiple ergodic average. The complexity of X is usually measured by entropy. This talk concerns on the entropy of multiplicative subshifts on N^d and trees, and shows our results about their entropy formulae or estimates.
