Resumen de Asymptotics of eigenvalues for a class of singular Kreĭn strings

Harald Woracek

• A Kreĭn string is (essentially) a pair ?[?,?] where 0

  We show that for a class of strings defined by a weaker growth restriction the spectrum is discrete, the integral on the right side is still finite, and the asymptotic behaviour of the eigenvalues is determined by the above formula.
