Expression and Perturbation of Approximative Dual Frames
Based on the frame theory of Hilbert space and by using the method of construction of dual frames,the notion of approximative dual frame was introduced,two explicit expressions of an arbitrary approximative frame were established,some perturbation results of approximative dual frames were obtained.
