For self-similar $P$ asymptotic formulas for eigenvalues are obtained. In this paper we consider two cases of self-similarity of $P$: 1) arithmetic degenerate, and 2) non-arithmetic.11 pages, 1 tableFunctional Analysis34L20; 34B09Indefinite Sturm--Liouville problem for some classes of self-similar singular weightstext
