The separation modulus of unitarily invariant matrix norms

If $X=(M_n(\mathbb{R}),\|\cdot\|)$ is a unitarily invariant normed space on , then we prove (via exact computations for a Jacobi orthogonal random matrix ensemble) that the spectral gap of the Laplacian with Dirichlet boundary conditions on the unit ball $B_X$ of $X$ satisfies $λ(X)\asymp n^3 \|I\|^2$.

Extension of the Total Least Square Problem Using General Unitarily Invariant Norms

, 2004
Let m, n, p be positive integers such that m ≥ n + p. Suppose (A, B) ∈ C m×n × C m×p, and let P(A, B) = {(E, F) ∈ C m×n × C m×p: there is X ∈ C n×p such that (A − E)X = B − F}. The total least square problem concerns the determination of the existence

The Stability of the Unit Balls of Symmetric and Unitarily Invariant Norms

, 1994
A compact convex set #KAPPA# is called stable if the midpoint mapping, #KAPPA#x#KAPPA##->##KAPPA#, (#chi#,#gamma#)#->#(#chi#+#gamma#)/2, is open.
