It is formed of those points in ˇ, for which the shortest distance occurs at more than one normal. This note shows how to generalize to arbitrary dimensions the result of S. In other words, it is the union over all xin Xof the cut loci of each x, in the usual sense. Two views of the cut locus (dark) and conjugate locus (grey) from a point on the periodic surface of revolution given by equation (5). The basic tool is Hironaka&39;s theory of.
