Spaces of solutions in case of maps from a K3-surface to the cotangent bundle of a complex projective space are computed. A relationship between harmonic spinors of a generalized nonlinear Dirac operator and solutions of the Cauchy-Riemann-Fueter equation are established.Cosmetic changes onlyDifferential GeometryMathematical Physics53C43; 53C26; 58J99text
