Martín Fiz Martín Fiz Martín Fiz Martín (born 3 March 1963 in Vitoria-Gasteiz, Álava) is a former long-distance runner from Spain, who won the marathon at the 1994 European Championships in Athletics in Helsinki and repeated his success at the 1995 World Championships in Athletics in Gothenburg. The same year he captured the title in the Rotterdam Marathon. At the 1996 Summer Olympics in Atlanta Fiz came fourth in the Athletics at the 1996 Summer Olympics - Men's marathon. A year later he won a silver medal at the 1997 World Championships in Athletics in Athens, finishing behind his countryman Abel Anton.
Abel transform single discontinuity, one has to introduce shifts for any of them to come up with a generalized version of the inverse Abel transform which contains "n" additional terms, each of them corresponding to one of the "n" discontinuities. The Abel transform is one member of the FHA cycle of integral operators. For example, in two dimensions, if we define "A" as the Abel transform operator, "F" as the Fourier transform operator and "H" as the zeroth-order Hankel transform operator, then the special case of the Projection-slice theorem for circularly symmetric functions states that: In other words, applying the Abel transform
