Estimates of the norm of the Mercer kernel matrices with discrete orthogonal transforms
The authors prove some inequalities related to the \(\ell_2\)-norm asymptotic of a Mercer matrix \((K(x_i,x_j))_{1\leq i,j\leq n}\) \(n\) where \(K:X\times X\to \mathbb R\) is defined on a space \(X\times X\) with a probability measure.
