comment Covariant derivative as a connection on a vector bundle
So, a connection is always a $\Gamma(E) \to \Gamma(E\otimes T^*M)$ function, and since there is a bijection between the spaces of covariant derivatives and connections (obtained from the contraction), a covariant derivative uniquely defines a connection ?

comment Covariant derivative as a connection on a vector bundle
I get that, my question is why would the new object be considered a connection as well ?

comment Completion of absolute value on an integral domain
For example, I thought of associating each integer with a constant sequence having that value, and then constructing the corresponding coset, but I am not sure that would be an injection.

comment Continuous spectral theorem example
OK thank you ! I have a "soft" question connected to your answer: are Dirac distributions eigenvectors of the operator $T$, if you were to consider distributions instead of functions ?

Thank you, this is more detailed than the Wikipedia article, on the same example.
