Título: Isoparametric surfaces in E(κ,τ)-spaces Conferenciante: José M. Manzano, Universidad Complutense de Madrid. Abstract: We provide an explicit classification of the following four families of surfaces in any homogeneous 3-manifold with 4-dimensional isometry group: isoparametric surfaces, surfaces with constant principal … Continue reading

Título: Some results of invariant theory for CR-manifolds. Conferenciante: Yen-Chang Huang, Xinyang Normal University . Abstract: In this talk, I will introduce some recent works of invariant theory on CR manifolds. After a briefing of CR manifolds, some integral invariants … Continue reading
