Abstract
A nonstandard q-deformed Euclidean algebra Uq(ison), based on the definition of the twisted q-deformed algebra Uqson) (different from the Drinfeld–Jimbo algebra Uq(son)), is defined. Infinite dimensional representations R of Uq(ison) are described. Explicit formulas for operators of these representations in the orthonormal basis are given. The spectra of the operators R(Tn) corresponding to a q-analogue of the infinitesimal operator of shifts along the n-th axis are described. Contrary to the case of the classical Euclidean Lie algebra ison, these spectra are discrete and spectral points have one point of accumulation.
