摘要：

By using the contour integral representation of delta-function and the technique of integration within an ordered product of operators, we point out that the q-deformed creation operator possesses the eigenkets. A set of new completeness and orthogonality relations composed of the kets and bras which are not mutually Hermitian conjugates are derived. Application of the completeness relation in constructing the generalized P-representation of density operator is demonstrated. (C) 2010 American Institute of Physics. [doi:10.1063/1.3485041]
