一类二阶超越系数非齐次线性微分方程解的零点与级

In this paper, we investigate the complex oscillation of the differential equation f‘‘ B1f‘ B0f=F1 whtere B0,B1,F≠0 are order meromorphic functions having only finitely many poles and the order of B1 is larger than that of B0.We obtain some precise estimates of the order of growth and of the exponent of convergence of the zero-sequence of solutions for this equation.
