Definition:Lp Space

Definition
Let $\struct {X, \Sigma, \mu}$ be a measure space, and let $p \in \closedint 1 \infty$.

Let $\map {\mathcal L^p} {X, \Sigma, \mu}$ be the Lebesgue $p$-space of $\struct {X, \Sigma, \mu}$.

Let $\sim$ be the almost-everywhere equality equivalence relation on $\map {\mathcal L^p} {X, \Sigma, \mu}$.

We define the $L^p$ space $\map {L^p} {X, \Sigma, \mu}$ as the quotient set:
