摘要
给出了微分方程 y″ +P(x) y′+Q(x) y =0的幂级数解 y = ∞n=0an(x -x0 ) n 其系数满足二项递推公式an+ p =f(n)an
A method is given to find the radius o f convergence of the power series y=∞n=0a n(x-x 0) n with the coefficients satisfying the binomial recurring formula a n+p =f(n)a n, where y is the solution of the the differential eq uation y″+P(x)y′+Q(x)y=0.
