摘要: Gell‐Mann and Hartle have proposed a significant generalization of quantum theory in which decoherence functionals perform key role. Isham–Linden–Schreckenberg given penetrating analysis for L(H), where H is finite dimensional (dimension greater than 2). In this note their conjecture on the significance boundedness verified. particular, it shown that when d bounded functional associated with von Neumann algebra A, then, provided A has no direct summand type I2, can be represented as difference between semi‐innerproducts A.
