Eigenvalues for Some Complex In nite Tridiagonal Matrices
Maria Malejki · Journal of Advances in Mathematics and Computer Science · 2018
The discrete spectrum for an unbounded operator J dened by a special innite tridiagonal complex matrix is approximated by the eigenvalues of its orthogonal truncations. Let σ(J) means the spectrum of the operator J and where Limn→∞λn is the s...
