Abstract

We study conformal minimal two-spheres immersed into the quaternionic projective space Pn by using the twistor map. We present a method to construct new minimal two-spheres with constant curvature in Pn, based on the minimal property and horizontal condition of Veronese map in complex projective space. Then we construct some concrete examples of conformal minimal two-spheres in Pn with constant curvature 2/n, n = 4, 5, 6, respectively. Finally, we prove that there exist conformal minimal two-spheres with constant curvature 2/n in Pn (n≥7):
