講演者:Marian Ioan Munteanu 氏(University "Al.I.Cuza" of Iasi)
題目:Contact CR-submanifolds in Sasakian spheres: new examples.
概要:In this talk we focus on those proper contact CR-submanifolds, which areas closed as possible to totally geodesic ones in the seven dimensionalspheres endowed with its canonical structure of a Sasakian space form.We give a complete classification for such a submanifold havingdimension 4 and describe the techniques of the study. We present alsosome very recent developments concerning dimension 5 and propose furtherproblems in this direction.
