This paper analyzes stability and perturbations of chi-phi frames and bessel sequences in banach spaces, suggesting their practical applications.
Frames in relation to certain sequence spaces, specifically Chi-Phi frames, were introduced and studied. Further investigations into Chi-Phi frames and their various characterizations can be found. The stability and perturbation of frames are crucial in practical applications and have been extensively studied. In this paper, we examine the stability and perturbations of Chi-Phi frames and Chi-Phi Bessel sequences in Banach spaces, extending two important propositions from [3]and [7], respectively.
