    "abstract": "When Alice and Bob have different quantum knowledges or state assignments\n(density operators) for one and the same specific individual system, then the\nproblems of compatibility and pooling arise. The so-called first\nBrun-Finkelstein-Mermin (BFM) condition for compatibility is reobtained in\nterms of possessed or sharp (i. e., probability one) properties. The second BFM\ncondition is shown to be generally invalid in an infinite-dimensional state\nspace. An argument leading to a procedure of improvement of one state\nassifnment on account of the other and vice versa is presented.",
