On ϕ-recurrent generalized Sasakian-space-forms

Lobachevskii Journal of Mathematics, 2012
The authors study \(\phi\)-recurrent generalized Sasakian-space-forms, i.e. almost contact metric manifolds satisfying additional conditions for the curvature tensor. In particular, the curvature tensor of such manifolds is of the form \[ \begin{multlined} R(X,Y)Z = f_1(g(Y,Z)X-g(X,Z)Y)+f_2(g(X,\phi Z)\phi Y-g(Y,\phi Z)\phi X+2 g(X,\phi Y)\phi Z ...

Semi-symmetric generalized Sasakian-space-forms

2023
Summary: We show that semi symmetric and pseudo symmetric generalized Sasakian-space-forms are Einstein when \((0, 6)\)-tensors satisfy \(R \cdot R = 0, R\cdot R = L_RQ(g,R), R\cdot C = 0, R\cdot C = L_CQ(g,C)\), and \(C \cdot C = 0\), where \(C\) is quasi conformal curvature tensor. Further we discuss about Ricci solitons.
