## Abstract Oscillation criteria for self‐adjoint fourth‐order differential equations were established for various conditions on the coefficients __r__(__x__) > 0, __q__(__x__) and __p__(__x__). However, most of these results deal with the case when lim~__x__ β†’ ∞~∫^__x__^~1~__q__(__s__) __ds__ < +
