摘要
研究了一类分数阶广义非线性扰动热波方程.首先用奇异慑动方法,求出了分数阶广义非线性扰动热波方程初始边值问题的任意次近似解析解.然后利用泛函分析不动点定理证明了它的一致有效性,最后简述了它的物理意义.求得的近似解析解,弥补了单纯用数值方法求模拟解的不足.
A class of generalized fractional nonlinear disturbed thermal wave equation is considered.Firstly,the arbitrary order approximate analytic solutions for the fractional generalized nonlinear disturbed thermal wave equation initial boundary value problem was constructed by using the singular perturbation method.And the uniformly valid asymptotic expansion was proofed by using the fixed point theory of the functional analysis.The physical sense of the solution was stated simply.The approximate analysis solution makes up not enough the simple numerical simulation solution.
