Primes

Primes

represents the domain of prime numbers, as in x∈Primes.

Details

  • x∈Primes evaluates only if x is a numeric quantity.
  • Simplify[expr∈Primes] can be used to try to determine whether an expression corresponds to a prime number.
  • The domain of primes is taken to be a subset of the domain of integers.
  • PrimeQ[expr] returns False unless expr explicitly has head Integer.
  • Primes is output in TraditionalForm as TemplateBox[{}, Primes]. This typeset form can be input using pris.

Simplifications involving prime numbers:

Primes represents the set of positive integers that are prime:

PrimeQ gives True if an integer, positive or negative, is prime:

PrimeQ returns True for explicit numeric primes and False otherwise:

Element remains unevaluated when it cannot decide whether an expression is a prime:
