On boundary interpolation for matrix valued Schur functions
A number of interpolation problems are considered in the Schur class of p × q matrix valued functions S that are analytic and contractive in the open unit disk. The interpolation constraints are specified in terms of nontangential limits and angular derivatives at one or more (of a finite number of) boundary points. Necessary and sufficient conditions for existence of solutions to these problem...
متن کامل[hal-00788395, v1] Parametrization of matrix-valued lossless functions based on boundary interpolation
This paper is concerned with parametrization issues for rational lossless matrix valued functions. In the same vein as previous works, interpolation theory with metric constraints is used to ensure the lossless property. We consider here boundary interpolation and provide a new parametrization of balanced canonical forms in which the parameters are angular derivatives. We finally investigate th...
متن کاملNonpathological Lyapunov functions and discontinuous Carathéodory systems
Differential equations with discontinuous righthand side and solutions intended in Carathéodory sense are considered. For these equations sufficient conditions which guarantee both Lyapunov stability and asymptotic stability in terms of nonsmooth Lyapunov functions are given. An invariance principle is also proven.
متن کاملMinimal H 2 Interpolation in the Carathéodory Class
For (c,,..., c„) in C, let C(cx,..., c„) denote the class of functions/(z) = 1 + cxz + ■ ■ • + cnz" + 2*>_„+ia*z* which are analytic and satisfy Re/(z) > 0 in the unit disc. The unique function of least H2 norm in C(cx,. .., c„) is explicitly determined. In this paper we consider a minimal interpolation problem at the origin, for the class H2 n C, where H2 denotes the well-known Hardy space for...
متن کاملA Constrained Nevanlinna-pick Interpolation Problem for Matrix-valued Functions
Recent results of Davidson-Paulsen-Raghupathi-Singh give necessary and sufficient conditions for the existence of a solution to the NevanlinnaPick interpolation problem on the unit disk with the additional restriction that the interpolant should have the value of its derivative at the origin equal to zero. This concrete mild generalization of the classical problem is prototypical of a number of...
