RICCI SOLITONS ON HOPH HYPERSURFACES IN SASAKIAN SPACE FORM
Abstract
fM2n+1(c). The rst, we prove that Hoph hypersurfaces of a Sasakian space form
fM2n+1(c < 1) with two distinct principal curvatures is shrinking and for c 1,
Hoph hypersurfaces with two distinct principal curvatures of a Sasakian space form
fM2n+1(c) does not admit a Ricci soliton. We show that there is not any Hoph hyper-
surfaces with two distinct principal curvatures in a Sasakian space form fM2n+1(c)
with a -Ricci soliton (and Ricci soliton) such that potential vector eld is the Reeb
vector eld.
Then we prove that Hoph hypersurfaces in Sasakian space form fM2n+1(c) with
c = 1 does not admit a - Ricci soliton with potential vector eld U and we show
that Ricci soliton on Hoph hypersurfaces M in Sasakian space form fM2n+1(c <
