题目：On some types of Lyapunov exponents and entropy for Z^k-actions

时间：4月21日（周五）下午4点至5点

地点：管研楼1518教室

摘要：Random Lyapunov exponents and directional Lyapunov exponents for 

smooth Z^k-actions are investigated. The relation between them and the 

Lyapunov exponents of the generators are given. As applications, the 

formulas of random entropy, directional entropy and Friedland's entropy  

are obtained.
