Ill-posed inverse problems based on Volterra-type equations

Inverse problems based on Volterra equations are, as a rule, well-posed. But in the case when a function should be retrieved in the range which is wider than the range where the right side of the equation is given, the solution appears an ill-posed inverse problem. A number of physical examples in electromagnetics is given, and it is shown that such inverse problems could be successfully solved on the basis of Tikhonov´s method of general discrepancy
