Smallest eigenvalues of Hankel matrices for exponential weights

We obtain the rate of decay of the smallest eigenvalue of the Hankel matrices I t j+kW2(t ) dt n j,k=0 for a general class of even exponential weights W2 = exp(−2Q) on an interval I . More precise asymptotics for more special weights have been obtained by many authors.  2004 Elsevier Inc. All rights reserved.
