Abstract
We show that a compact complex manifold has no non-trivial nef -classes if there is a non-isomorphic bimeromorphic map isomorphic in codimension to a compact K\"ahler manifold with . In particular, there exist infinitely many isomorphic classes of smooth compact Moishezon threefolds with no nef and big -classes. This contradicts a recent paper (Strongly Jordan property and free actions of non-abelian free groups, Proc. Edinb. Math. Soc., (2022): 1--11).
