Measures on projections and physical states
Research output: Contribution to journal › Journal article › Research › peer-review
It is shown that a finitely additive measure on the projections of a von Neumann algebra without I2 and II1 summands is the restriction of a state. A definition of a physical state is proposed, and it is shown that such a physical state on a simple C*-algebra with unit is a state.
