چکیده
|
In this paper, we mainly consider the growth and the oscillation of solutions of the second order nonhomogeneous linear differential equationsf''+ h1(z) e^p(z)f'+h0(z) e^q(z)f = f (z),where p (z), q(z) are nonconstant polynomials such that deg (p) = deg(q) and hj (z) ≡ 0 (j = 0, 1), f (z) are meromorphic functions of finite order having only finitely many poles such that ρ (h0)
