Combining the methods of Cuenin [2019] and Borichev-Golinskii-Kupin [2009, 2018], we obtain the so-called Lieb-Thirring inequalities for non-selfadjoint perturbations of an effective Hamiltonian for bilayer graphene.

On spectral properties of compact Toeplitz operators on Bergman space with logarithmically decaying symbol and applications to banded matrices
Autor: Mahamet Koita, Belco Touré, Stanislas Kupin, Sergey Naboko
Let $L^2(D)$ be the space of measurable square-summable functions on the unit disk. Let $L^2_a(D)$ be the Bergman space, i.e., the (closed) subspace of analytic functions in $L^2(D)$. $P_+$ stays for the orthogonal projection going from $L^2(D)$ to $

ON THE INSTABILITY OF THE ESSENTIAL SPECTRUM FOR BLOCK JACOBI MATRICES
Autor: Sergey Naboko, Stanislas Kupin
Publikováno v: Constructive Approximation
Constructive Approximation, Springer Verlag, 2018, 48 (3), pp.473-500
We are interested in the phenomenon of the essential spectrum instability for a class of unbounded (block) Jacobi matrices. We give a series of sufficient conditions for the matrices from certain classes to have a discrete spectrum on a half-axis of

A remark on analytic Fredholm alternative
Autor: Leonid Golinskii, Stanislas Kupin
Publikováno v: Letters in Mathematical Physics
Letters in Mathematical Physics, Springer Verlag, 2017, 107 (3), pp.467-474
We apply a recent result of Borichev-Golinskii-Kupin on the Blaschke-type conditions for zeros of analytic functions on the complex plane with a cut along the positive semi-axis to the problem of the eigenvalues distribution of the Fredholm-type anal

Orthogonal polynomials and a generalized Szegő condition
Autor: Sergey A. Denisov, Stanislas Kupin
Publikováno v: Comptes Rendus Mathematique. 339:241-244
Asymptotical properties of orthogonal polynomials from the so-called Szegő class are very well-studied. We obtain asymptotics of orthogonal polynomials from a considerably larger class and we apply this information to the study of their spectral beh

A Blaschke-type condition for analytic functions on finitely connected domains. Applications to complex perturbations of a finite-band selfadjoint operator
Autor: Stanislas Kupin, Leonid Golinskii
Publikováno v: Journal of Mathematical Analysis and Applications
Journal of Mathematical Analysis and Applications, Elsevier, 2012, 389 (2), pp.705-712
This is a sequel of a recent article by Borichev-Golinskii-Kupin, where the authors obtain Blaschke-type conditions for special classes of analytic functions in the unit disk which satisfy certain growth hypotheses. These results were applied to get

Classical Schur analysis is intimately connected to the theory of orthogonal polynomials on the circle [Simon, 2005]. We investigate here the connection between multipoint Schur analysis and orthogonal rational functions. Specifically, we study the c
