Abstract:
Given a minimal Legendre immersion L in S2n+1 and n >= k >= 1 we prove that n+1-k is an eigenvalue of the Hodge-Laplacian acting on k and (k-1)-forms on L. In particular we show that the eigenspaces Eigk(n+1-k) and Eigk-1(n+1-k) are at least of dimension . The paper was motivated by an earlier result of the author concerning minimal Lagrangian immersions in hyperKähler manifolds.
