Regularity results for almost minimal oriented hypersurfaces in \(\mathbb R^n\). (English) Zbl 1191.35007
Quaderni del Dipartimento Matematica dell’Universita de Lecce 1984,1. Lecce: Dipartimento di Matematica dell’Universit√† di Lecce. iii, 92 p. (1984).
This work is intended as an introduction to the regularity theory of oriented boundaries in \(\mathbb R^n\) which are almost minimal for the area functional. It is based partly on an earlier manuscript which contained the proof of the main theorem presented below, and partly on lecture notes for a course by the author at the University of Lecce.
The reader is presumed to have some knowledge of the basic facts concerning Caccioppoli sets: sections 2.1 to 2.4 of the book of U. Massari and M. Miranda [Minimal surfaces of codimension one. Amsterdam etc.: North-Holland (1984; Zbl 0565.49030)] will serve the scope. With the exception of a few “classical” inequalities, the proofs of which can also be found in the cited book, the exposition is essentially self-contained.
