On equation y”-q(t)y of finite type, 1-special, with the same central dispersion of the first kind. (English) Zbl 0709.34031

Some properties of linear differential equations of the type \(y''=q(t)y\) which have the same central dispersion of the first kind on their definition interval are investigated. According to the author central dispersions of the first kind are functions which map “the zeros of an arbitrary solution \(y''\) of the equation above “onto the zeros of the same solution”.
