1. On Landscape of Nonconvex Regularized Least Squares for Sparse Support Recovery (IEEE SPL VOL. 29, 2022)

(1) In the first paragraph of Sec. III, when we define the set S_{\Delta}, there should be an additional constraint | S | \le s besides the separation constraint.

(2) In the statement of Lemma 2 and Theorem 1, it should be Delta/N >= 2.5/f_c

(3) The above two typos will not affect the technical derivations and the correctness of the results.
