The Solution of the Problem of Determining the Density of Heat Sources in a Rod

Abstract: 

We give a solution of a problem of determining the density of heat sources in the bav, which is set to a fixed temperature, if the temperature is given approximately. Mathematically it is the problem of finding uniform approximations to the right-hand side of the ordinary differential equation when uniform approximations to the solution and values of error are known. First using the so-called discontinuous Steklov operator we construct families of operators which give stable uniform approximations to a function and its first and second derivatives, and then with their help we propose the method of solving the formulated problem. For a certain class of solutions error estimations are given.
