## Goce Chadzitaskos## Coherent states over open chainWe construct coherent states for $q$-deformed harmonic oscillators when $q$ is the $(M+1)^{th}$ root of the unity. For the construction we use para--Grassmann variables over $M$ dimensional complex space $\mbox{\bf C}^M $. Moreover, using the coherent states, Berezin symbols and the star product are expressed. |
