On the q-exponential of matrix q-Lie algebras

open access: yesSpecial Matrices, 2017
In this paper, we define several new concepts in the borderline between linear algebra, Lie groups and q-calculus.We first introduce the ring epimorphism r, the set of all inversions of the basis q, and then the important q-determinant and corresponding ...

Reductions and conservation laws for BBM and modified BBM equations

open access: yesOpen Mathematics, 2016
In this paper, the classical Lie theory is applied to study the Benjamin-Bona-Mahony (BBM) and modified Benjamin-Bona-Mahony equations (MBBM) to obtain their symmetries, invariant solutions, symmetry reductions and differential invariants. By observation

Generalized Bicomplex Numbers and Lie Groups

open access: yes, 2013
In this paper, we denone the generalized bicomplex numbers and give some algebraic properties of them. Also, we show that some hyperquadrics in R4 and R42 are Lie groups by using generalized bicomplex number product and obtain Lie algebras of these Lie ...

Solving Quantum Dynamics with a Lie-Algebra Decoupling Method

open access: yesPRX Quantum
Quantum technologies rely on the control of quantum systems at the level of individual quanta. Mathematically, this control is described by Hamiltonian or Liouvillian evolution, requiring the application of various techniques to solve the resulting ...
