A singular version of Leighton's comparison theorem for forced quasilinear second order differential equations

Ondřej Došlý, Jaroslav Jaroš (2003)

Archivum Mathematicum

Similarity:

We extend the classical Leighton comparison theorem to a class of quasilinear forced second order differential equations ( r ( t ) | x ' | α - 2 x ' ) ' + c ( t ) | x | β - 2 x = f ( t ) , 1 < α β , t I = ( a , b ) , ( * ) where the endpoints a , b of the interval I are allowed to be singular. Some applications of this statement in the oscillation theory of (*) are suggested.

On a conjecture about an integral criterion for oscillation

Uri Elias, Anton Škerlík (1998)

Archivum Mathematicum

Similarity:

We discuss an open question of Kiguradze and Chanturia about Property A and Property B for the equation y ( n ) + p y = 0 . The proposed integral criterion is proved in a few cases.
