| Abstract: | In this paper we determine all the bijective linear maps on the space of bounded observables which preserve a fixed moment or the variance. Nonlinear versions of the corresponding results are also presented. |
| Keywords: | Bounded observable Mean value Moments Variance Deviation Linear preservers Isometry |
