Spheres with parallel mean curvature in $\mathbb{S}^{2}\times \mathbb{H}^{2}$

It is known that a surface with parallel mean curvature vector field in a Riemannian product of two surfaces of constant Gaussian curvature carries a holomorphic quadratic differential. In this paper, we consider the Riemannian product of a sphere and a hyperbolic plane of opposi...
