comment Estimate loss of information due to a low rank approximization by SVD
I would say entropy. But any hint will be appreciated.

comment Function of two integers that has not repeated values
Just a performance issue. An equation would be faster.

comment Operations between temporal discrete intervals
Thank you vadim. If I got your point, you suggest to consider $E_1$ as a subset of $T$, therefor if I need to interset it with $E_2$, that is the usual sets intersection. That is for sure the best and simplest solution, but someonewant me to formalize the problem as if the domain is the set of couples $TT = \{<x,y> : x,y \in T \}$.

comment Prove this property of the SVD
Hi, I think that what you say is not correct; infact $VV^T = I$ by definition, but $V_k V_k^T$ isn't!

OK!Thank you for your answer, it made me realize how my question was stupid :)
