T1 The occurrence of prime numbers revisited A1 Tapia Moore, Ernesto A1 Tapia Yañez, José K1 Occurrence of prime numbers K1 occurrence of composite numbers K1 autocatalysis K1 activator-inhibitor systems AB Based on an arithmetical and autocatalytic approach, the authors propose a solution for the occurrence of prime numbers. Exact arithmetical calculations are provided for: the closest prime to any given positive integer (or any number of bigger or smaller primes from that integer); the quantity of prime (and composite) numbers between 1 and any positive integer; the quantity of prime (and composite) numbers between any two positive integers.
