Harmonic Maps of the Two-Sphere into a Complex Grassmann Manifold II

Abstract

where qT is a complex-valued one-form, defined up to a factor of absolute value 1. This form qp defines a complex structure on M. For x E M the space f(x) has an orthogonal space f(x) ' of dimension n - k. We denote by [ f(x)] and [ f(x) '] their corresponding projective spaces, of dimensions k - 1 and n - k - 1,
