comment How to show a compact sets has finite measure?
In page 75 of the linked .pdf it is stablished that $\mu$ is locally finite wich is exactly the same thay say that $\mu(K)\lt\infty$ for any subset $K$ compact. In order to have compact sets with finite measure it's enough for the measure to be $\sigma-$finite.

comment For $x∈\mathbb{R}^n$ , let $B(x,r)$ denote the closed ball in $\mathbb{R}^n$(with Euclidean norm) of radius $r$ centered at $x$
Please consider accept the answers they give you. How do I accept an answer?

comment Showing that $\nu \ll \mu$ implies $\forall \epsilon > 0$, $\exists \delta > 0$ s.t. $\mu(A) < \delta \implies \nu(A) < \epsilon$
What is you definition of $\nu \ll \mu$?

comment Clarifications about the definition of algebraic systems and algebraic structures
Following the definitions, an algebraic system is for example $\langle \Bbb Z, +\rangle$ and an algebraic structure is $\langle \Bbb Z,+,\leq\rangle$

revised $f\geq 0$, continuous and $\int_a^b f=0$ implies $f=0$ everywhere on $[a,b]$

answered Does $f(x)$ is continuous and $f = 0$ a.e. imply $f=0$ everywhere?
