K. Naimark et M. Solomyak, ON THE EIGENVALUE BEHAVIOR FOR A CLASS OF OPERATORS RELATED TO SELF-SIMILAR MEASURES ON R(D), Comptes rendus de l'Academie des sciences. Serie 1, Mathematique, 319(8), 1994, pp. 837-842
We obtain the sharp order of growth of the eigenvalue distribution fun
ction for the operator in the Sobolev space H-0(1) (Omega), generated
by the quadratic form integral(Omega) \u\(2) d mu, where Omega subset
of R(d) is a bounded domain and mu is a probability self-similar fract
al measure on Omega.
