《タイトル》Projective K3 surfaces containing Levi-flat hypersurfaces<br />
<br />
《講演概要》<br />
In May 2017, I reported on the gluing construction of a K3 surface at Seminar on Geometric Complex Analysis.<br />
Here, by the gluing construction of a K3 surface, I mean the construction of a K3 surface by holomorphically gluing two open complex surfaces which are the complements of tubular neighborhoods of elliptic curves included in the blow-ups of the projective planes by nine points.<br />
As of 2017, it was an open problem whether a projective K3 surface can be obtained by the gluing construction. Recently, I and Takato Uehara found a very concrete way to construct a projective K3 surface by the gluing method. As a corollary, we obtained the existence of non-Kummer projective K3 surface with compact Levi-flat hypersurfaces.<br />
In this talk, I will explain the detail of the concrete gluing construction of such a K3 surface.<br />
