The embedding of Haagerup \(L^p\) spaces
The author gives a proof of a theorem belonging to the mathematical folklore, stating that whenever \(N\) is an expected von Neumann subalgebra of a von Neumann algebra \(M\), there is, for each \(p\), a natural isometric embedding of \(L^p(N)\) into \(L^p(M)\).
