On the two-point boundary value problem for quadratic second-order differential equations and inclusions on manifolds (Q2491411)

Summary: The two-point boundary value problem for second-order differential inclusions of the form \[ (D/dt)\dot{m}(t)\in F(t,m(t),\dot{m}(t)) \] on complete Riemannian manifolds is investigated for a couple of points, nonconjugate along at least one geodesic of Levi-Civitá connection, where \(D/dt\) is the covariant derivative of Levi-Civitá connection and \(F(t,m,X)\) is a set-valued vector with quadratic or less than quadratic growth in the third argument. Some interrelations between certain geometric characteristics, the distance between points, and the norm of right-hand side are found that guarantee solvability of the above problem for \(F\) with quadratic growth in \(X\). It is shown that this interrelation holds for all inclusions with \(F\) having less than quadratic growth in \(X\), and so for them the problem is solvable.
