摘要
本文利用有限元方法建立了求解一类含有低阶未知系数的抛物方程反问题的数值公式,论证了近似解的收敛性和误差阶估计.
This paper deals with the inverse probletns for a class of parabolic equations with lower order unknown coefficient and the additional information on the solution of integral type. Numerical formulas for solving the inverse problems are constructed by finite element method, and the error order estimates are derived in L_2 and L_∞ norms.
