 Jun 7 comment How do I show that the following is a basis for the weak topology on $X$? Maybe you'll find this thread useful: math.stackexchange.com/questions/305808/… Jun 7 comment How do I show that the following is a basis for the weak topology on $X$? What is $p$ and what do you mean by that set being a semi-norm? Jun 7 comment How do I show that the following is a basis for the weak topology on $X$? Isn't this the definition of the weak topology? What is your definition? Jun 7 answered When is the series converges? Jun 7 comment When is the series converges? Remember to include the absolute values inside the root. Jun 7 comment Is this a metric on the shift space? Did you check the axioms of a metric space, or what makes you "think" yes? Is there some particular part that puzzles you?

Jun 7 comment Error in the reasoning? @dietervdf. but that's the thing. $d(x,a)=r$ does not translate to $x\in \partial B(a,r)$. Jun 5 revised Error in the reasoning? edited tags Jun 5 answered Error in the reasoning? Jun 5 comment Error in the reasoning? @dietervdf: That property does hold. Note that $\overline{B}(x,r)$ is not the closure of any given set of our interest. The upper bar is just a notation here, different from closure.

Because it's an additive group. Thanks.
