In this paper we give the local existence in time of differentiable solutions to the quasi-linear initial boundary value problem for a class of symmetric hyperbolic systems with characteristic boundary of constant multiplicity.

We obtain a condition on the spectrum of the characteristic operator for the zero solution of Volterra difference equations on a Banach space to be exponen-tially asymptotically stable. Moreover, we apply some results obtained here to derive stability properties for some differential equations with piecewise continuous delays.

Let L be a Lagrangian submanifold of a Kähler manifold (M, J, ω). In the present paper, we give the integral formula of the Maslov index of L. Using this, we investigate relations between symplectic topological conditions and the mean curvature vector of L when (M, J, ω) is a Kähler-Einstein manifold with nonzero Ricci curvature.

We prove several nonexistence theorems for proper harmonic maps and harmonic morphisms between space forms of constant negative curvature under the assumption that they are sufficiently regular up to the ideal boundary.
