comment Norm of operator between two $L^p$ spaces?
Thanks for the reply; I made an edit to clarify what I was asking about the relation between the $|| \cdot ||_{p \to q}$ norm and the $ || \cdot ||_p$ and $ || \cdot ||_q$ norms.

comment If $f(x)$ and $g(x)$ are Riemann integrable and $f(x)≤h(x)≤g(x)$, must $h(x)$ be Riemann integrable? (Repost)
Without the assumption, certainly not: on your domain of definition, let $f$ be the constant function equal to $0$, $g$ the constant function equal to $1$, $h$ the indicator function on the rationals.

comment Deciding whether this map is well defined.
$f(1 + 20\mathbb{Z}) = 1 + 15\mathbb{Z}$. But $1 + 20\mathbb{Z} = 21 + 20\mathbb{Z}$ and $f(21 + 20\mathbb{Z}) = 21 + 15\mathbb{Z} = 6 + 15\mathbb{Z} \neq 1 + 15\mathbb{Z} $.

Am I correct in saying that $C_1'$ is indeed a cycle (no repeated vertices) because the paths contained in both $C_1$ and $C_2$ that you've chosen are consecutive paths?

@ajon Yes, that's right.
