报告摘要：

In this talk, we will discuss r-neutralized local entropy and r-neutralized entropy. We will review some background on measures of maximal entropy, measures of maximal Hausdorff dimension, and neutralized entropy. We obtain formulas for the r-neutralized local entropy in smooth systems. In particular, for certain hyperbolic systems, we prove the existence of ergodic measures that maximize the r-neutralized entropy. Based on joint work with Qiujie Qiao.
