Abstract: | We establish monotonicity inequalities for the r-area of a complete oriented properly immersed r-minimal hypersurface in Euclidean
space under appropriate quasi-positivity assumptions on certain invariants of the immersion. The proofs are based on the corresponding
first variational formula. As an application, we derive a degeneracy theorem for an entire r-minimal graph whose defining
function ƒ has first and second derivatives decaying fast enough at infinity: Its Hessian operator D2 ƒ has at least n − r null eigenvalues everywhere. |
