报告摘要  In this talk, we review the development of Ledrappier-Young theory (Ledrappier-Young entropy formula) which is a generalization of the famous Pesin theory (Pesin entropy formula).

报告摘要  Pesin theoy and Ledrappier-Young theory are both based on Oseledets’ Multiplicative Ergodic Theorem. In this talk we discuss the subtle formulation of the theorem in deterministic smooth dynamical system as a first step for the two theories.

报告摘要 Beside Oseledets’ Multiplicative Ergodic Theorem, other tools in probability theory are in need for establishing Pesin theoy and Ledrappier-Young theory. For this end we introduce the martingale theory and would lead the audience to see how it works in proving the theory.
