Does anyone know where I can find or purchase these works in the particular the first reference "Some aspects of functional equations," 1979 J. Dhombres,which is relatively well cited in Azcel &J. Dhombres,(1989). I cannot even seem to find an online bookseller, that has it in stock ; ie so that I can purchase if if need be. If anyone knows a where one can purchase a copy of this or the other works mentioned below that would be much appreciated?
Any help
