Oscillation of a class of second-order linear impulsive differential equations

摘要

In this paper, we investigate the oscillation of a class of second-order linear impulsive differential equations of the form { ( a ( t ) [ x ′ ( t ) + λ x ( t ) ] ) ′ + p ( t ) x ( t ) = 0 , t ≥ t 0 , t ≠ t k , x ( t k + ) = b k x ( t k ) , x ′ ( t k + ) = c k x ′ ( t k ) , k = 1 , 2 , … . By using the equivalence transformation and the associated Riccati techniques, some interesting results are obtained. MSC:34A37, 34C10.
