Isoperimetric surfaces with boundary, II

Abraham Frandsen, Donald Sampson and Neil Steinburg

Vol. 259 (2012), No. 2, 307–313
Abstract

Following our previous work with Dorff and Lawlor, we extend results for the so-called equitent problem of fixed boundary and fixed volume. We define sufficient conditions, which in 2 and 3 are also necessary, for local minima to be piecewise spherical, and we show that these are area-minimizing in their homotopy class. We also give new examples of these surfaces in 2 and 3.
