Abstract:
We continue to study a composite model of a generalized oscillator generated by an N-periodic Jacobi matrix. The foundation of the model is a system of orthogonal polynomials connected to this matrix for N=3,4,5. We show that such polynomials do not exist for N⩾6.
Keywords:
generalized oscillator, Chebyshev polynomial, classical moment problem.
