3 unusual facts about Gödel numbering for sequences


Gödel numbering for sequences

Using the Chinese remainder theorem, we can prove that implementing \beta as

By an ingenious use of Chinese remainder theorem, we can define constructively such a recursive function \beta (using simple number-theoretical functions, all of which can be defined in a total recursive way) fulfilling the "specifications" given above.

Using the fundamental theorem of arithmetic is a straightforward way, but there are also more economic approaches, e.g. using pairing function combined with Chinese remainder theorem in a sophisticated way.
