I wonder if anyone can suggest any short reading about basic understanding of L space or L2 space (not wikipedia) I know nothing about it, googled around, but doesn't seem to find things helping me solve some problems.(adsbygoogle = window.adsbygoogle || []).push({});

First, there's this question: For what range of μ is |x|^μ in L2(-1,1)

I thought the def for L2( [a,b]) = {x:(a,b) -> c | x2 is finite}, x2 = integrate x(t)^2 over t from a to b

but it's confusing, where's t? Also, it doesn't seem to be able to solve this problem

Any suggestion? Thanks.
