摘要 研究一类具有整函数系数的二阶线性微分方程解的复振荡.在系数满足一定条件下方程的任一非零解具有无穷增长级. The complex oscillation of the solution to a class of second-order linear differential equations with entire coefficients is studied in the paper.When the coefficients are satisfied with a certain condition,any nonzero solution to the equation will be infinite order.
