Statement

The twin prime conjecture asserts that there are infinitely many twin primes. We assert that there are infinitely twin primes by asserting that for every n : ℕ there is a twin prime that is larger than n.

is-twin-prime-ℕ : ℕ → UU lzero
is-twin-prime-ℕ n = (is-prime-ℕ n) × (is-prime-ℕ (succ-ℕ (succ-ℕ n)))

twin-prime-conjecture : UU lzero
twin-prime-conjecture =
  (n : ℕ) → Σ ℕ (λ p → (is-twin-prime-ℕ p) × (leq-ℕ n p))
