On the structure of composite odd integer and prime numbers

Giuseppe Buffoni


With the expression ''structure of an odd integer'' we mean the set of properties of the integer n which specifies the odd integer 2n+1 and brings about its behaviour. These properties of n, for both composite and prime numbers, are expounded in detail, together with their geometrical implications. In this context,
a set, in a two dimensional space, where all the composite odd integers in [2a+1, 2n+1] are localized, is illustrated.
