On totally contact umbilical submanifolds of a manifold with a sasakian 3-structure

In our paper [5] we proved that any totally contact umbilical submanifold M of a manifold with a Sasakian 3-structure with dim <IMG SRC="http:/img/fbpe/rtfiuz/v27n3/art04ec1.gif" WIDTH=18 HEIGHT=18>> 1, <FONT FACE=Symbol>"</FONT>x<FONT FACE=Symbol>Î</FONT...

Description
Summary:In our paper [5] we proved that any totally contact umbilical submanifold M of a manifold with a Sasakian 3-structure with dim <IMG SRC="http:/img/fbpe/rtfiuz/v27n3/art04ec1.gif" WIDTH=18 HEIGHT=18>> 1, <FONT FACE=Symbol>"</FONT>x<FONT FACE=Symbol>Î</FONT>M , is totally contact geodesic. In the present paper we solve the remaining cases. Namely, when dim <IMG SRC="http:/img/fbpe/rtfiuz/v27n3/art04ec1.gif" WIDTH=18 HEIGHT=18 > or = 0, or dim <IMG SRC="http:/img/fbpe/rtfiuz/v27n3/art04ec1.gif" WIDTH=18 HEIGHT=18 > or = 1, M is totally contact geodesic or an intrinsic sphere respectively.<br>En nuestro trabajo [5] probamos que cualquier subvariedad con contacto umbilical completo de una variedad con una estructura-3 Sasakian con dim <IMG SRC="http:/img/fbpe/rtfiuz/v27n3/art04ec1.gif" WIDTH=18 HEIGHT=18>> 1, para todo x que pertenece a M, es de contacto geodésico total. En el presente trabajo resolvemos los casos restantes. A saber, cuando dim <IMG SRC="http:/img/fbpe/rtfiuz/v27n3/art04ec1.gif" WIDTH=18 HEIGHT=18 > o = 0 ó dim <IMG SRC="http:/img/fbpe/rtfiuz/v27n3/art04ec1.gif" WIDTH=18 HEIGHT=18 > o = 1, M es de contacto geodésico total o una esfera intrínseca. rectivamente.
