What is $p$ and what do you mean by that set being a semi-norm?

Isn't this the definition of the weak topology? What is your definition?

answered If $f$ is a group homomorphism from $(\mathbb{Z},+)$ to $(\mathbb{Q}-\{0\},.)$ such that $f(2)=\frac{1}{3}$, then find $f(-8)$.

@dietervdf. but that's the thing. $d(x,a)=r$ does not translate to $x\in \partial B(a,r)$.
