Minimal two-spheres with constant curvature in ℍ{\mathrm{P}}^n

Abstract

We study conformal minimal two-spheres immersed into the quaternionic projective space ℍ{\mathrm{P}}^n by using the twistor map. We present a method to construct new minimal two-spheres with constant curvature in ℍ{\mathrm{P}}^n, 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 ℍ{\mathrm{P}}^n 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 ℍ{\mathrm{P}}^n (n≥7):

Key words： Quaternionic projective space; twistor map; minimal two-spheres; Veronese sequence
