Approximately Hadamard matrices and Riesz bases in random frames

Xiaoyu Dong, Mark Rudelson

An $n \times n$ matrix with $\pm 1$ entries which acts on $R^{n}$ as a scaled isometry is called Hadamard. Such matrices exist in some, but not all dimensions. Combining num…

The Smallest Singular Value of a Shifted Random Matrix

Xiaoyu Dong

Let $R_{n}$ be a $n \times n$ random matrix with i.i.d. subgaussian entries. Let $M$ be a $n \times n$ deterministic matrix with norm $∥ M ∥ \leq n^{γ}$ where $1/2 < γ < 1$ . The g…
