On oscillation and asymptotic property of a class of third order differential equations N. Parhi, Seshadev Pardi (1999) Czechoslovak Mathematical Journal Similarity: In this paper, oscillation and asymptotic behaviour of solutions of y ' ' ' + a ( t ) y ' ' + b ( t ) y ' + c ( t ) y = 0 have been studied under suitable assumptions on the coefficient functions a , b , c ∈ C ( [ σ , ∞ ) , R ) , σ ∈ R , such that a ( t ) ≥ 0 , b ( t ) ≤ 0 and c ( t ) < 0 .
