The pinching constant for closed minimal submanifolds of high codimension in the sphere

Abstract

Let Mn be a closed minimal submanifold in the unit sphere š•Šn+q with ngeqslant 3 and qgeqslant 2. Let S be the squared length of its second fundamental form and Smax=maxp∈ MS(p). We prove that if M is not totally geodesic, then Smax>2n/3+(nāˆ’2)/182.
