On the q-analogues of the Zassenhaus formula for dientangling exponential operators

R. Sridhar, R. Jagannathan

Katriel, Rasetti and Solomon introduced a $q$ -analogue of the Zassenhaus formula written as $e_{q}^{(A + B)}$ $=$ $e_{q}^{A} e_{q}^{B} e_{q}^{c_{2}} e_{q}^{c_{3}} e_{q}^{c_{4}} e_{q}^{c_{5}} ...$ , where $A$ and $B$ …

Quadratic algebras :Three-mode bosonic realizations and applications

V. SunilKumar, B. A. Bambah, R. Jagannathan

Quadratic algebras of the type $\lsb Q_0, Q_\pm \rsb$ $=$ $\pm Q_{\pm}$ , $\lsb Q_+, Q_- \rsb$ $=$ $a Q_{0}^{2} + b Q_{0} + c$ are studied using three-mode bosonic realizations. Matrix repres…
