Bochner and conformal flatness on normal complex contact metric manifolds
(Springer, 2010-10-10)
We will prove that normal complex contact metric manifolds that are Bochner flat must have constant holomorphic sectional curvature 4 and be Kähler. If they are also complete and simply connected, they must be isometric ...

Optimal inequalities, contact delta-invariants and their applications
(Malaysian Mathematical Sciences Society, 2013)
Associated with a k-tuple (n1, . . . , nk) ∈ S(2n + 1) with n ≥ 1, we define a contact δ-invariant, δc (n1, . . . , nk), on an almost contact metric (2n + 1)-manifold M. For an arbitrary isometric immersion of M into a ...
