In the first part of the paper, Azzouni's derivation-indicator view was presented. In the second part it is analyzed in a detailed way. It is shown, that many problems arise, which cannot be explained in a satisfactory way in Azzouni's theory, in particular the problem of the explanatory role of proof, of its epistemic role; the relationship between first-order and second-order versions of proofs...
The article is devoted to the problem of status of mathematical proofs, in particular it tries to capture the relationship between the real, 'semantic' notion of mathematical proof, and its formal (algorithmic) counterpart. In the first part, Azzouni's derivation-indicator view is presented in a detailed way. According to the DI view, there is a formal derivation underlying every real proof.
