Abstract:In this paper,the method for solving the inverse problem for a heat conduction equation in the reproducing kernel space is discussed.Employing unknown parameter p(t),the solution w(t,x) is exactly represented in the form of series.And considering additional condition,both the unknown parameter p(t) and the solution w(t,x) can be obtained.The solution of numerical example proves the method as simple and feasible.
Keywords:parameter indentification    inverse problem    reproducing kernel
