Rotational elliptic Weingarten surfaces in S2 × R and the Hopf problem

We prove that, up to congruence, there exists only one immersed sphere satisfying a given uniformly elliptic Weingarten equation in S2 × R, and it is a rotational surface. This is obtained by showing that rotational uniformly elliptic Weingarten surfaces in S2 × R have bounded second fundamental for...

Sumario:We prove that, up to congruence, there exists only one immersed sphere satisfying a given uniformly elliptic Weingarten equation in S2 × R, and it is a rotational surface. This is obtained by showing that rotational uniformly elliptic Weingarten surfaces in S2 × R have bounded second fundamental form together with a Hopf type result by J. A. Gálvez and P. Mira.
