WebOn the first variation of a varifold. Suppose M is a smooth m dimensional Riemannian manifold and k is a positive integer not exceeding m. Our purpose is to study the first variation of the k dimensional area integrand in M. Our main result is a regularity theorem for weakly defined k dimensional surfaces in M whose first variation of area is ... WebRemark. Note that if the variation is normal, that is, hV;e ii= 0 for all i, it follows that = 0 on @M, so the result is true for all normal variations, even without the boundary condition f tj@M = id @M. The second variation formula. We consider only normal variations of a minimal surface M: H= 0; @ tf= V = uN; where uis a function on M. ea sports cricket 2007 download and install
