Abstract:

For a given simply connected Riemannian surface $\Sigma$, we relate the problem of finding minimal isometric immersions of $\Sigma$ into $\mathbb{S}^2\times\mathbb{R}$ or
$\mathbb{H}^2\times\mathbb{R}$ to a system of two partial differential equations on $\Sigma$. We prove that a constant intrinsic curvature minimal surface in
$\mathbb{S}^2\times\mathbb{R}$ or $\mathbb{H}^2\times\mathbb{R}$ is either totally geodesic or part of an associate surface of a certain limit of catenoids in
$\mathbb{H}^2\times\mathbb{R}$. We also prove that if a non-constant curvature Riemannian surface admits a continuous one-parameter family of minimal isometric immersions into
$\mathbb{S}^2\times\mathbb{R}$ or $\mathbb{H}^2\times\mathbb{R}$, then all these immersions are associate.
