Replacing objects of mathematics by other objects with the same name

Zbigniew Semadeni — 2007

Didactica Mathematicae

The purpose of the paper is to introduce and analyse the following conception: by an ontic shift $X \tilde{\to} X^{''}$ we mean an (explicit or hidden) replacement of a mathematical object $X^{'}$ called $X$ by a different object $X^{''}$ which is also called $X$ and is to play the role of $X^{'}$ . If $X^{'}$ and $X^{''}$ are sets, then $X^{'} \neq X^{''}$ means that these sets are different in the usual sense. Otherwise $X^{'}$ and $X^{''}$ may stand for basic concepts of mathematics such as, e.g., point, straight line, natural number, addition of natural numbers, (standard) real...
