A positive rational number q belongs to the pmin-min-prime-limit, called the '''minimal prime limit''', for a given prime number pmin if and only if it can be factored into primes (with positive or negative integer exponents) of size more than or equal to pmin. | A positive rational number q belongs to the pmin-min-prime-limit, called the '''minimal prime limit''', for a given prime number pmin if and only if it can be factored into primes (with positive or negative integer exponents) of size more than or equal to pmin. | ||
In other words, a positive rational number q belongs to the pmin-limit if and only if all primes of its factorization into primes are left-bounded to pmin. | In other words, a positive rational number q belongs to the pmin-min-prime-limit if and only if all primes of its factorization into primes are left-bounded to pmin. | ||
