报告摘要：
During this talk, pre-image entropy and entropy-like invariants are first introduced. Some questions will be presented and then talk about conditional entropy's propositions. Variational principle, subadditivity and commutativity properties for entropy and pressure are also shown. Therefore, some new results are also exhibited to see what we can do next step for semigroup action on entropy.
