Teissier problem aims to characterize the equality case of Khovanskii-Teissier type inequality for (1,1)-classes on a compact Kaehler manifold. When each of the involved (1,1)-classes is assumed to be nef and big, this problem has been solved by the previous works of Boucksom-Favre-Jonsson, Fu-Xiao and Li. In this talk, we shall introduce our recent work which settles the case that the involved (1,1)-classes are just assumed to be nef. By constructing examples, it is shown that our results are optimal.
