The space of positive Lagrangians in an almost Calabi-Yau manifold is an open set in the space of all Lagrangian submanifolds. A Hamiltonian isotopy class of positive Lagrangians admits a natural Riemannian metric gamma, which gives rise to a notion of geodesics. We study geodesics of positive O-n(R) invariant Lagrangian spheres in n-dimensional A(m) Milnor fibers. We show the existence and uniqueness of smooth solutions to the initial value problem and the boundary value problem. In particular, we obtain examples of smooth geodesics of positive Lagrangians in arbitrary dimension. As an application, we show that the Riemannian metric gamma induces a metric space structure on the space of positive O-n(R) invariant Lagrangian spheres in the above-mentioned Milnor fibers.
