comment Proof that the sum of two real measurable functions is measurable.
Thank you, I will make that assumption to solve the problem. Do you think this question can be answered to any $\sigma$-algebra?

Yes, I do. However the $\sigma$-algebra here is not specified, so I didn't think that borelians would help. But go on, please.

Not imediatelly, no. Would you enlighten me?

Thanks! I need some more time to flag as correct answer.

Thank you a lot. ( :

comment Proof that any finite subset of a lattice has a supremum.
Would you bother to give me a proof? Because before asking here I saw that my claim implied in associativity and tried to prove it, but I failed.

So, if I understood correctly, proving my claim implies in proving associativity, right?

Thank you for your answer, but I did not prove that $\vee$ is an associative operation.
