Abstract：
By virtue of the algebra of the q-deformed fermion oscillators, the q-deformed charged fermion coherent states and SU(3) charged,hypercharged fermion coherent states are discussed.The explicit forms of the two kinds of coherent states mentioned above are obtained by making use of the completeness of base vectors in theq-fermion Fock space.By comparing the q-deformed results with the ordinary results,it is found that the q-deformed charged fermion coherent states and SU(3)charged, hypercharged fermion coherent states are automatically reduced to the ordinary charged fermion coherent states and SU(3)charged,hypercharged fermion coherent states if the deformed parameter q→1.
