Some Remarks on a Limit‐Point Condition

where q(t) is locally Lebesgue-integrable on [a, oo), may be classified according to the behaviour of the solutions of the differential equation xy(t) = 0 for large values of t. In particular, following Weyl [17], we say that the formal operator x is of limit-circle type at oo if every solution of xy(t) = 0 is of class «Sf[a, oo); conversely, if one or more independent solutions of xy(t) = 0 are not of class S£\a, oo), then T is said to be of limit-point type at oo. In the recent paper [4] of Eastham, the following sufficient condition for limitpoint type was given:
