Interpretation of the Schur-Cohn test in terms of canonical systems
Masatoshi Suzuki
We solve direct and inverse problems for two-dimensional (quasi) canonical systems related to exponential polynomials of a specific but sufficiently general type. The approach to t…
Chains of reproducing kernel Hilbert spaces generated by unimodular functions
Masatoshi Suzuki
We present a method to construct a chain of reproducing kernel Hilbert spaces controlled by a first-order system of differential equations from a given unimodular function satisfyi…
An inverse problem for a class of lacunary canonical systems with diagonal Hamiltonian
Masatoshi Suzuki
Hamiltonians are 2-by-2 positive semidefinite real symmetric matrix-valued functions satisfying certain conditions. In this paper, we solve the inverse problem for which recovers a…
An inverse problem for a class of canonical systems and its applications to self-reciprocal polynomials
Masatoshi Suzuki
A canonical system is a kind of first-order system of ordinary differential equations on an interval of the real line parametrized by complex numbers. It is known that any solution…
