Abstract

In this paper we show boundary monotonicity formulae for rectifiable varifolds having a C1,αC^{1,\alpha} "boundary". In particular, we show that the area ratios of balls centered at this "boundary'' satisfy a nice monotonicity formula, similar to that for interior balls (proved in Allard's paper "On the first variation of a varifold''). This extends the boundary monotonicity formulae of Allard (see "On the first variation of a varifold- boundary behavior''), which require that the boundary is C1,1C^{1,1}. As a corollary, Allard's boundary regularity results extend to this case and provide a regularity result for rectifiable varifolds with a C1,αC^{1,\alpha} ``boundary''.
