Optimality condition and iterative thresholding algorithm for [Formula: see text] -regularization problems

This paper investigates the [Formula: see text] -regularization problems, which has a broad applications in compressive sensing, variable selection problems and sparse least squares fitting for high dimensional data. We derive the exact lower bounds for the absolute value of nonzero entries in each...
