## Transformations of linear second order ordinary differential equations.(English)Zbl 0644.34029

From the author’s abstract: The transformation $$z(t)=\alpha (t)y+\beta (t)y'$$ of solutions y of a linear second order ordinary differential in general form is considered and a differential equation for z(t) is derived. Previous results concerning such problem are discussed.
