Family Seiberg-Witten equation on Kahler surface and $Ï_i(\Symp)$ on multiple-point blow ups of Calabi-Yau surfaces

Yi Du

Let $I ¨ $ be a Kahler form on $M$ , which is a torus $T^{4}$ , a $K 3$ surface or an Enriques surface, let $M # n CP^{2}$ be $n -$ point Kahler blowup of $M$ . Suppose that…

Quasi-positive curvature and projectivity

Yiyang Du, Yanyan Niu

In this paper, we first prove that a compact KÃ¤hler manifold is projective if it satisfies certain quasi-positive curvature conditions, including quasi-positive $S_2^\perp,\, S_2^…
