Summary: The notion of Limit-Computable Mathematics (LCM) is introduced. LCM is a fragment of classical mathematics in which the law of excluded middle is restricted to \(\Delta^0_2\). We can give an accountable computational interpretation to the proofs of LCM. The computational content of LCM-proofs is given by Gold’s limiting recursive functions, which is the fundamental notion of learning theory. LCM is expected to be a right means for “Proof Animation”, which was introduced by the first author [see S. Hayashi, R. Sumitomo and K. Shii, Theor. Comput. Sci. 272, 177–195 (2002; Zbl 0984.68138)]. LCM is related not only to learning theory and recursion theory, but also to many areas in mathematics and computer science such as computational algebra, computability theories in analysis, reverse mathematics, and many others.
