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 $z^{p} \frac{d ^{p + 1}}{d z ^{p + 1}}$ $(p = 0, 1, 2, ...)$ acting on classical Bargmann space $B_{p}$ …

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 $β_{k} = μ k$ and off-diagonal entries $α_{k} = iλk k + 1$ ; $1 \leq k \leq n$ , $n \in N$ and $i^{2} = - 1$ wh…

On the complete indeterminacy and the chaoticity of generalized operator of Heun in Bargmann space

Abdelkader Intissar

In Communications in Mathematical Physics, no. 199, (1998), we have considered the Heun operator $H = a^{*} (a + a^{*}) a$ acting on Bargmann space where $a$ and $a^{*}$ …
