By using the recursion relations found in the framework of N=2 SuperYang-Mills theory with gauge group SU(2), we reconstruct the structure of theinstanton moduli space and its volume form for all winding numbers. Theconstruction is reminiscent of the Deligne-Knudsen-Mumford compactification anduses an analogue of the Wolpert restriction phenomenon which arises in the caseof moduli spaces of Riemann surfaces.Comment: 1+8 pages, LaTeX.
