ABSTRACT
This chapter focuses on a very particular kind of function that is applied to the complex plane and is called zeta function. It is marked with Greek sign zeta. The B. Riemann zeta function is an extremely important function of mathematics that is intimately related with results surrounding the prime number theory. "In number theory, zeroes of the zeta function are the notes, prime numbers are the chords, and theorems are the symphonies". To link the "zeta theory" with yet another important concept in psychoanalysis is repression. According to J. Lacan primary repression is a fixed signifying chain that starts forming during the mirror stage. Lacan says that "the presence of the signifier in the Other is, in effect, a presence usually closed to the subject, because it usually persists in a state of repression, and because from there it insists on representing itself in the signified by means of its repetition compulsion".
