摘要：

We systematically develop Weyl-Titchmarsh theory for singular differential operators on arbitrary intervals (a; b) subset of R associated with rather general differential expressions of the type Tf = 1/r (-(p[f' + sf])' + sp [f ' + sf] + qf ), where the coefficients p, q, r, s are real-valued and Lebesgue measurable on (a; b), with p not equal 0, r > 0 a.e. on (a, b), and p(-1), q, r, s is an element of L-loc(1) ((a, b); d x), and f is supposed to satisfy f is an element of AC (loc) ((a, b)), p [f' + sf] is an element of AC (loc) ((a, b))
