摘要 考虑四分之一平面内分数阶热传导方程的柯西问题,使用最优滤波正则化方法给出了该问题的近似解,并采用Fourier变换技术得到了H?lder类型的误差估计. The Cauchy problem for the sideways fractional heat equation is discussed in the quarter plane.An approximate solution of the problem is given using the optimal filtering regularization method,and the H?lder type error estimates are obtained by using Fourier transforms.
