| Popis: | For varifolds whose first variation is representable by integration, we introduce the notion of indecomposability with respect to locally Lipschitzian real valued functions. Unlike indecomposability, this weaker connectedness property is inherited by varifolds associated with solutions to geometric variational problems phrased in terms of sets, $G$ chains, and immersions; yet it is strong enough for the subsequent deduction of substantial geometric consequences therefrom. Our present study is based on several further concepts for varifolds put forward in this paper: real valued functions of generalised bounded variation thereon, partitions thereof in general, partition thereof along a real valued generalised weakly differentiable function in particular, and local finiteness of decompositions. Comment: This is the second paper of a series of three papers which shall supersede arXiv:1709.05504 by the same authors. 58 pages (v1: 43 pages), no figures, added treatment of varifolds with free boundary which includes an isoperimetric lower density ratio bound in 9.22 and results in Theorem E and Corollary 3 |
