Let $X_N$ be a $N\times N$ matrix whose entries are i.i.d. complex random variables with mean zero and variance $\frac{1}{N}$. We study the asymptotic spectral distribution of the eigenvalues of the c...

Abstract: We derive a method to reconstruct Gaussian signals from linear measurements with Gaussian noise. This new algorithm is intended for applications in astrophysics and other sciences. The start...
Dynamical locality and covariance: What makes a physical theory the same in all spacetimes?

Abstract: The question of what it means for a theory to describe the same physics on different spacetimes (of the same dimension) is discussed. To this end, a previously introduced functorial descript...

Abstract: We extend the results about the fluctuations of the matrix entries of regular functions of Wigner matrices to the case of sample covariance random matrices.
