Dissipation and c-Entropy in Nevanlinna-Pick Interpolation

We study interpolation L-systems realizing finite Nevanlinna-Pick data sets and analyze their structural and quantitative characteristics. Explicit formulas are derived for the c-entropy and dissipation coefficient, two intrinsic invariants that describe the dissipative structure of interpolation L-systems. These quantities depend only on the geometric placement of interpolation nodes in ${\mathbb{C}}_{+}$, attaining maximal finite values for purely imaginary nodes. The interpolation model ${\mathrm{\Theta }}_{\mathrm{\Delta }}$ and its unitary equivalents reveal that these invariants form a direct link between analytic interpolation data and the dynamical properties of L-systems. Particular attention is given to symmetric configurations, where the impedance function admits an explicit rational representation and a natural physical interpretation in terms of equivalent $LC$-networks.
