  1. 1. Central bank power: a matter of coordination rather than money supply

    Författare :Ingemar Bengtsson; Fastighetsvetenskap; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; ekonomiska system; ekonomisk teori; economic theory; economic systems; econometrics; Economics; inflation; units of accounts; money; focal points; Central banks; ekonomisk politik; economic policy; ekonometri; Nationalekonomi;

    Sammanfattning : After an introductory chapter, the hypothesis is made in chapter two: that central bank power to control the rate of inflation rests on the bank’s ability to achieve a role as a focal point for inflation. Inflation is a measure of changes in the general price level, the price level is an index of individual prices, and to predict future price levels is thus to predict future prices on individual items.

  2. 2. Chronic pain : epidemiological studies in a general population

    Författare :H. Ingemar Andersson; Bengt Scherstén; Göran Ejlertsson; Ido Leden; Calle Bengtsson; Sweden Lund University Department of Community Health Sciences; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; chronic pain; epidemiology; health care; Epidemiology; Epidemiologi; MEDICINE; MEDICIN;

    Sammanfattning : The aim was to study the epidemiology of chronic pain (> 3 months duration) and factors associated to pain prevalence, prognosis, health care and medication in a general population. A cross-sectional mailed survey to a random population sample (n = 1806) was followed by a clinical examination and a prospective study of three selected groups. LÄS MER

  3. 3. Holonomy in Quantum Information Geometry

    Författare :Ole Andersson; Ingemar Bengtsson; Boris Shapiro; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; Theoretical Physics; teoretisk fysik;

    Sammanfattning : In this thesis we provide a uniform treatment of the two most popular non-adiabatic geometric phases for dynamical systems of mixed quantum states, namely those of Uhlmann and of Sjöqvist et al. We develop a holonomy theory for the latter which we also relate to the already existing theory for the former. LÄS MER

  4. 4. Configurations in Quantum Information

    Författare :Kate Blanchfield; Ingemar Bengtsson; Erik Sjöqvist; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Physics; fysik;

    Sammanfattning : Measurements play a central role in quantum information. This thesis looksat two types: contextual measurements and symmetric measurements. Contextualityoriginates from the Kochen-Specker theorem about hidden variablemodels and has recently undergone a subtle shift in its manifestation. LÄS MER

  5. 5. Geometry and foundations of quantum mechanics

    Författare :Kate Blanchfield; Ingemar Bengtsson; Anthony Sudberry; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; Theoretical Physics; teoretisk fysik;

    Sammanfattning : This thesis explores three notions in the foundations of quantum mechanics: mutually unbiased bases (MUBs), symmetric informationally-complete positive operator valued measures (SICs) and contextuality. MUBs and SICs are sets of vectors corresponding to special measurements in quantum mechanics, but there is no proof of their existence in all dimensions. LÄS MER
