Integral Geometry and Convolution Equations 124 in die Europa durch dieIntegral geometry deals with the problem of determining functions by their integrals over given families of sets. These integrals de? ne the corresponding integraltransformandoneofthemainquestionsinintegralgeometryaskswhen this transform is injective. On the other hand, when we work with complex measures or forms, operators appear whose kernels are non trivial but which describe important classes of functions. Most of the questions arising here
