Recovery of sparsest signals via $ℓ^{q}$ -minimization

Qiyu Sun

In this paper, it is proved that every $s$ -sparse vector $x \in R^{n}$ can be exactly recovered from the measurement vector $z = A x \in R^{m}$ …

Wiener's Lemma for Infinite Matrices II

Qiyu Sun

In this paper, we introduce a class of infinite matrices related to the Beurling algebra of periodic functions, and we show that it is an inverse-closed subalgebra of ${\mathcal B}…
