    A Népkönyvtári Központból került a MTA Könyvtár és Információs Központ állományába az osztrák gyógyszerkönyv - Pharmacopoea Austriaca - harmadik, javított kiadásának egy csonka példánya. A címoldalon Pécs Városi Muzeum Könyvtára, illetve Pécs Szab. Kir. Város Közművelődési Könyvtára pecsétje látható, valamint egy kézírásos possessori bejegyzés: J. Hermann. A címlap verzóján egy hosszabb, kézírásos lista olvasható, amely egy mohácsi patika árukészletét tartalmazza, J. M. Herdy aláírásával, keltezés nélkül

    Is Quantum Mechanics Compatible with an Entirely Deterministic Universe?

    A b s t r a c t It will be argued that 1) the Bell inequalities are not equivalent with those inequalities derived by Pitowsky and others that indicate the Kolmogorovity of a probability model, 2) the original Bell inequalities are irrelevant to both the question of whether or not quantum mechanics is a Kolmogorovian theory as well as the problem of determinism, whereas 3) the Pitowsky type inequalities are not violated by quantum mechanics, hence 4) quantum mechanics is a Kolmogorovian probability theory, therefore, 5) it is compatible with an entirely deterministic universe.Comment: 15 pages, (compressed and uuencoded) Postscript (188 kb), preprint 94/0

    On the generalized Kesten--McKay distributions

    We examine the properties of distributions with the density of the form: 2Ancn2c2x2πj=1n(c(1+aj2)2ajx),% \frac{2A_{n}c^{n-2}\sqrt{c^{2}-x^{2}}}{\pi \prod_{j=1}^{n}(c(1+a_{j}^{2})-2a_{j}x)}, where c,a1,,anc,a_{1},\ldots ,a_{n} are some parameters and AnA_{n} a suitable constant. We find general forms of An% A_{n}, of kk-th moment and of kk-th polynomial orthogonal with respect to such measures. We also calculate Cauchy transforms of these measures. We indicate connections of such distributions with distributions and polynomials forming the so-called Askey--Wilson scheme. On the way, we prove several identities concerning rational symmetric functions. Finally, we consider the case of parameters a1,,ana_{1},\ldots ,a_{n} forming conjugate pairs and give some multivariate interpretations based on the obtained distributions at least for the cases n=2,4,6.n=2,4,6.Comment: 14 page
