    Asymptotics of the discrete spectrum for complex Jacobi matrices
    (2014) Malejki, Maria
    The spectral properties and the asymptotic behaviour of the discrete spectrum for a special class of infinite tridiagonal matrices are given. We derive the asymptotic formulae for eigenvalues of unbounded complex Jacobi matrices acting in $l^2(\mathbb{N})$.
