    Asymptotic expansion of large eigenvalues for a class of unbounded Jacobi matrices
    (Wydawnictwa AGH, 2020) Harrat, Ayoub; Zerouali, El Hassan; Zieliński, Lech
    We investigate a class of infinite tridiagonal matrices which define unbounded self-adjoint operators with discrete spectrum. Our purpose is to establish the asymptotic expansion of large eigenvalues and to compute two correction terms explicitly.
