“…Gromov cites the work of Thurston [18], Inoue-Yano [13] and Savage [16], in which positivity is verified for compact manifolds that are real hyperbolic, negatively curved and locally symmetric quotients of SL(n, R)/SO(n, R), respectively. Moreover, Gromov [10] shows that characteristic classes may be represented using bounded cohomology classes implying positivity for several additional classes of locally symmetric spaces.…”
