We will be concerned with the focal boundary value problem (-1)'~An[p(t)Any (h,t,y(t) ..... An-ls/(t)), Ail/(0) = A'~+ill(b+ 1) ----0, 0 \_< i \_< n --1. Using cone theory in a Bausch space, we show that under certain Bumptioas on f, this focal boundary value problem has two positive solutions. In t
