Let n=p1a1p2a2⋯ptat be the prime factorization of n. Define ω(n)=t and Ω(n)=a1+a2+…+at. We aim to prove or disprove the following statements for any fixed positive integer k and positive reals α and β:
i) ω(n)ω(n+k)>α
ii) Ω(n)Ω(n+k)<β.
To address statement (i), we need to show that limsupn→∞ω(n)ω(n+k)=∞. This can be demonstrated by considering the behavior of ω(p+k) for prime p. Specifically, we show that limsupp→∞ω(p+k)=∞.
We start by examining the sum ∑p≤xω(p+k). For some y=xδ with 0<δ<21, let ωy(n) denote the number of prime factors of n that are ≤y. It can be shown that ω(n)=ωy(n)+O(1). Thus,
p≤x∑ω(p+k)=p≤x∑ωy(p+k)+O(logxx).
Using the Bombieri-Vinogradov Theorem, we obtain:
ℓ≤y∑π(x;ℓ,−k)=ℓ≤y∑ℓ−1lix+O(logAxx),
where π(x;ℓ,−k) counts primes p≤x such that p≡−k(modℓ).
Summing over primes ℓ≤y, we get:
ℓ≤y∑ℓ−11=loglogy+O(1).
Therefore,
p≤x∑ω(p+k)=π(x)loglogx+O(logxx).
Assuming ω(p+k)=O(1) leads to a contradiction, implying limsupp→∞ω(p+k)=∞. Hence, limsupn→∞ω(n)ω(n+k)=∞, proving statement (i).
For statement (ii), note that ω(n)≤Ω(n). Therefore, Ω(n)Ω(n+k)<β follows from ω(n)ω(n+k)>α by choosing appropriate α and β.
Thus, both statements are proven to be true.
The answer is: \boxed{\text{True}}.
