Neighborhood of a compact curve whose intersection matrix has a positive eigenvalue (Japanese)
[ 講演概要 ]
Let $C$ be a connected compact complex curve of a non-singular complex surface. We will show that, if the intersection matrix of the curve $C$ has a positive eigenvalue, then there is a neighborhood $V$ of $C$ and a strictly plurisubharmonic function on $V\setminus C$ which increases logarithmically near $C$.
As an application, we show that the complement of $C$ is a proper modification of an affine variety under the additional assumption that the surface is connected and compact.
This talk is based on a joint work with Tetsuo Ueda.
