A maths student with lots of questions... I also answer to others when I can, which for the time being is rare but I hope will improve!

comment Quadratic residue modulo $p$ iff quadratic residue module $p^k$
No, but if I knew that, would there be a simple argument?

comment Quadratic residue modulo $p$ iff quadratic residue module $p^k$
Unfortunately I am not familiar with the Lemma and hoped getting away without using it... I will have a precise look at it if there is no other easy solution :) and yes, my previous comment is wrong. Thanks

comment Quadratic residue modulo $p$ iff quadratic residue module $p^k$
e.g. if $k=1$, write $x^2=a+pr$ and show that $r$ is divisible by 2 by looking at $x^2=a+pr \;(\text{mod }2)$ right? thank you

comment Mapping cylinder is a CW complex
@Carsten Schultz: I see what is happening, but I can't prove formally that the k-skeleton really is the one you describe, could you help me with that please?

@Grigory M: Yes, but I don't understand exactly what is happening. As we are only working with $X\sqcup I$ here, I thought it would maybe give me some intuition understanding this particular case first.

ok, thanks. I don't know exactly how it works once a question has been declared a duplicate by five people and it is in fact not...

This is the reference which is mentionned, it does not answer the question.
