    "abstract": "In this paper combinatorial aspects of normal ordering arbitrary words in the\ncreation and annihilation operators of the q-deformed boson are discussed. In\nparticular, it is shown how by introducing appropriate q-weights for the\nassociated ``Feynman diagrams\u0027\u0027 the normally ordered form of a general\nexpression in the creation and annihilation operators can be written as a sum\nover all q-weighted Feynman diagrams, representing Wick\u0027s theorem in the\npresent context.",
