报告摘要：By using the variational approach, we prove the existence of Sinai-Ruelle-Bowen measures for partially hyperbolic $C^1$ diffeomorphisms with the mostly expanding properties. The same conclusion is obtained if one has the dominated splitting $E^{cs}\oplus E^{cu}$, where $\dim E^{cs}=1$ and $E^{cu}$ has the mostly expanding properties. When the diffeomorphisms are $C^{1+\alpha}$, we prove the basin covering property for both cases.
