Some results on fake quadrics
Jianqiang Yang
In this paper, we obtain several results on fake quadrics. First, we describe the cones \(\operatorname{Nef}(S)\) and \(\overline{\operatorname{Eff}(S)}\), and then provide a crite…

Topological characterization and Hodge structures of some rationally elliptic projective fourfolds
Jianqiang Yang
In this paper, we consider the rationally elliptic projective fourfolds that are holomorphically embedded into the complex projective eight-space . It is proved that…
