On The Third-Degree Continuous Cohomology of Simple Lie Groups
Journal of Lie Theory, Volume 29 (2019) no. 4, pp. 1007-1016
We show that the collection of connected, simple Lie groups that have non-vani\-shing third-degree continuous cohomology with trivial $\mathbb{R}$-coefficients consists precisely of all simple complex Lie groups and of $\widetilde{{\rm SL}_2(\mathbb{R})}$.
