WebMoreover, [19] proves that the induced metric on this submanifold is the third fundamental form of x(M). From this, computing the Riemann-Christoffel tensor of the third fundamental form metric corresponds to computing the curvature of the Gauss image. Similarly, [17] generalizes the Gauss map and third fundamental form to Kähler immersions.
