HIGHLIGHTS
- who: J. Spectr. Theory and collaborators from the (UNIVERSITY) have published the article: Perturbation determinants and discrete spectra of semi-infinite non-self-adjoint Jacobi operators, in the Journal: (JOURNAL)
- what: The authors focus on the roots of Pn just found.
SUMMARY
The case of study in the paper is the trace class perturbations of the discrete Laplacian J0, J nD1 an j C jbn j C j1 cn j/ and amp;lt; 1; see, e_g_[17, Lemma 2.3]. The authors study the Jost solutions by reducing the difference equation . . .
