New Spectral Properties of Imaginary part of Gribov-Intissar Operator
Abdelkader Intissar
In 1998, we have given in ([14] Intissar, A., Analyse de Scattering d'un opérateur cubique de Heun dans l'espace de Bargmann, Comm.Math.Phys.199 (1998) 243-256) the boundary condit…
Presentation of some elementary properties of Segal-Bargmann space and of unitary Segal-Bargmann transform with applications
Abdelkader Intissar
In this work, we present some elementary properties of Segal-Bargmann space and some properties of unitary Segal Bargmann transform with applications to differential operators aris…
Spectral analysis of some non-normal operators arising in Reggeon field theory
Abdelkader Intissar
In this work, we present a complete spectral study of a family of non-normal operators arising in Reggeon field theory. This family of operators is an original example who permit u…
On an application of generalized Jentzsch theorem to Gribov operator in Bargmann space
Abdelkader Intissar
{\it In Bargmann representation, the reggeon's field theory{\color{blue} [5]} is caracterized by the non symmetrical Gribov operator $\displaystyle{H_{λ',μ,λ} = λ' A^{*^{2}}A^{2} +…
On the chaoticity of some tensor product weighted backward shift operators acting on some tensor product Fock-Bargmann spaces
A. Intissar
In Advances in Mathematical Physics (2011) we showed that the weighted shift acting on classical Bargmann space …
On the zeros of some families of polynomials satisfying a three-term recurrence associated to Gribov operator
Abdelkader Intissar
We consider families of tridiagonal- matrices with diagonal and off-diagonal entries ; , and wh…
