Example. (Y-shape versus V-shape). Wewant to connect (concentration case r < 1fixed) a Dirac mass to two Dirac masses (ofweight 1/2 each) as in figure below, l and hare fixed. The value of the functional J isgiven byJ (γ) = x + 2 1−r√ (l − x) 2 + h 2 .Then the minimum is achieved forhx = l − √41−r− 1 .When r = 1/2 we have a Y-shape if l > hand a V-shape if l ≤ h.•h•xl•A Y-shaped path for r = 1/2.58
