Elementary Proof of a generalization of the Perron-Frobenius theorem in an ordered Banach space
Abdelkader Intissar
We work in an ordered Banach space with closed generating positive cone. We show that a positive compact operator has zero spectral radius or a positive eigenvector with the corres…

On regularized trace formula of Gribov semigroup genrated by the Hamiltonian of reggeon field theory in Bargmann representation
Abdelkader Intissar
In J. Math. Anal. App. 305. (2005), we have considered the Gribov operator\\ acting on Bargmann space where and $ H_{μ,λ} =μa^* a + \ı…

On chaoticity of the sum of chaotic shifts with their adjoints in Hilbert space and applications to some chaotic weighted shifts acting on some Fock-Bargmann spaces
Abdelkader Intissar
This article is intended to outline some the recent work by the author on the chaoticity of some specific bakward shift unbounded operators realized as differential operators actin…
