NOTES ON ORTHOGONAL ALMOST COMPLEX STRUCTURES ON THE RIEMANNIAN PRODUCTS

JP Journal of Geometry and Topology
In this paper, we show that there does not exist an orthogonal almost complex structure on a Riemannian product of a compact Riemann surface with negative constant curvature and a round 4-sphere. In addition, we prove that any orthogonal almost complex structure on a Riemannian product of a compact Riemann surface with negative constant curvature and a
