On sectional curvatures of \((\varepsilon)\)-Sasakian manifolds
Summary: We obtain some basic results for Riemannian curvature tensor of \((\varepsilon)\)-Sasakian manifolds and then establish equivalent relations among \(\varphi\)-sectional curvature, totally real sectional curvature, and totally real bisectional curvature for \((\varepsilon)\)-Sasakian manifolds.
