Abstract :
Given a partition R of w0, 1x: 0sr1Fr2F ??? FrN s1, let f r.sJ r.q
nNs1K ryrn., rgw0, 1x, where J r. is concave and K:wy1, 1x_ 04ªR is a
concave cusp with its point at 0. Necessary conditions on the partition R are
determined when R minimizes max0FrF1f r.smax1FnF Ny1 fn, where fns
maxrnFrFrnq1 f r.. It is shown that the partition that minimizes max1FnF Ny1 fn
also maximizes min1FnF Ny1 fn.
