topic：Willmore deformations between minimal surfaces in H^n and S^n
abstract： In this talk we will show that there exists Willmore deformations between minimal surfaces in H^n and S^n. The deformations of the Veronese two sphere and its generalization provide examples of complete minimal surfaces in H^4 with varying Willmore energy. Applying to a class of minimal surfaces in S^4, we show that they are non-rigid in the sense they admit global, non-trivial minimal deformations.
