Objetos, significados, representaciones semióticas y sentido.

In this paper, I want to illustrate a phenomenon related to the treatment and conversion of semiotic representations whose sense derives from a shared practice. On the one hand, the passage from one representation of a mathematical object to another, through transformations, maintains the meaning of the object itself, but on the other hand, sometimes can change its sense. This is shown in detail through an example, inserted within a wide theoretical framework that takes into account mathematical objects, their meanings and their representations. [ABSTRACT FROM AUTHOR]
