Teissier problem aims to characterize the equality case of Khovanskii-Teissier type inequality for (1,1)-classes on a compact Kahler 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 note, we shall settle 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. We also extend the results to the case when some of the (1,1)-classes are not necessarily nef.
