After presenting known examples, we give a proof for the non-existence of real analytic Levi flat hypersurface whose complement is 1-convex and Levi foliation is transversely affine in a compact Kähler surface. This is a joint work with Severine Biard (arXiv:2011.06379).</div></div><div class="">参加URLはこちら（Zoom URLは今学期間共通です．登録は一度大丈夫です）</div><div class=""><a href="https://zoom.us/meeting/register/tJ0vcu2rrDIqG9Rv5AT0Mpi37urIkJ1IRldB" class="">https://zoom.us/meeting/register/tJ0vcu2rrDIqG9Rv5AT0Mpi37urIkJ1IRldB</a><br class=""><br class="">今後の予定はこちら<br class=""><a href="https://www.ms.u-tokyo.ac.jp/seminar/geocomp/future.html" class="">https://www.ms.u-tokyo.ac.jp/seminar/geocomp/future.html</a><br class=""><br class="">講演者も募集中です。<br class=""><br class="">世話人<br class="">平地 健吾, 高山 茂晴</div></div>_______________________________________________<br class="">Geometry-ml mailing list<br class=""><a href="mailto:Geometry-ml@math.nagoya-u.ac.jp" class="">Geometry-ml@math.nagoya-u.ac.jp</a><br class=""><a href="https://mail.math.nagoya-u.ac.jp/mailman/listinfo/geometry-ml" class="">https://mail.math.nagoya-u.ac.jp/mailman/listinfo/geometry-ml</a><br class=""></div></body></html>
