Abstract
Let M be a semifinite von Neumann algebra, and let A be a tracial subalgebra of M. We show that A is a subdiagonal algebra of M if and only if it has the unique normal state extension property and is a τ-maximal tracial subalgebra, which is also equivalent to A having the unique normal state extension property and satisfying L2-density.
