Comparing Kahler cone and symplectic cone of one-point blowup of Enriques surface
We follow the study by Cascini-Panov on symplectic generic complex structures
on Kahler surfaces with $p_g=0$, a question proposed by Tian-Jun Li, by
demonstrating that the one-point blowup of an Enriques surface admits
non-Kahler symplectic forms. This phenomenon relies on the abundance of
elliptic fibrations on Enriques surfaces, characterized by various invariants
from algebraic geometry. We also provide a quantitative comparison of these
invariants to further give a detailed examination of the distinction between
Kahler cone and symplectic cone.
