Hello, The next Banach spaces webinar is on Friday April 23 at 9AM Central time. Please join us at https://unt.zoom.us/j/83807914306 Speaker: March Boedihardjo (UCLA) Title: Spectral norms of Gaussian matrices with correlated entries Abstract: We give a non-asymptotic bound on the spectral norm of a d×d matrix X with centered jointly Gaussian entries in terms of the covariance matrix of the entries. In some cases, this estimate is sharp and removes the sqrt(log d) factor in the noncommutative Khintchine inequality. Joint work with Afonso Bandeira.
