Inhomogeneous balanced non-Kähler metrics on complex projective spaces

We consider the cohomogeneity one action of $G_{p,q}=\mathrm{U}(p+1)\times\mathrm{U}(q+1)$ on $\mathbb{C}P^{p+q+1}$, where $p\geq q\geq 1$ and $p>1$. We characterize all $G_{p,q}$-invariant Riemannian metrics compatible with the canonical complex structure and obtain parametrizations of the invarian
