[Authors] Petrova, Yu. P. [Title] Spectral asymptotics for problems with integral constraints [AMS Subj-class] 34L20 Asymptotic distribution of eigenvalues, asymptotic theory of eigenfunctions 60G15 Gaussian processes [Abstract] We consider an eigenvalue problem for the ordinary differential operator of arbitrary order with integral constraints. We obtain the sharp asymptotics of eigenvalues. This result is applied to the problem of small ball probabilities for some $m$th order detrended Gaussian processes.
