“…It appears in condensed-matter and high-energy physics [31,40], and it is naturally studied in quasiconformal geometry (see for instance [29]). The study of symmetry problems in convex cones has recently attracted the interest of many authors, see for instance [6,12,13,22,25,36,37,42]. As far as the authors know, overdetermined capacity problems in convex cones have not been considered so far, even in the Euclidean case.…”
