Talk:Even Functions in 2-Lebesgue Space form Closed Subspace of 2-Lebesgue Space

I think it should be $\map {\LL^2} \R$ throughout, since $\map {L^2} \R$ should denote the $L^p$ space with $p = 2$. Caliburn (talk) 20:50, 4 July 2022 (UTC)
 * We also might want to specifically declare when the ambient measure space is dropped to write $\R$ in favour of $\struct {\R, \map {\mathrm {Leb} } \R, \lambda}$ or $\struct {\R, \map \BB \R, \lambda}$. Eg. in some cases we might want the $\sigma$-algebra to be only the Borel sets, or we might want the measure space to be complete so we'll have to use all Lebesgue measurable sets. We should therefore pick a default and then specify when it strays from that. Caliburn (talk) 21:32, 4 July 2022 (UTC)
