Contribution to understanding the mathematical structure of quantum mechanics

Probabilistic description of results of measurements and its consequences for understanding quantum mechanics are discussed. It is shown that the basic mathematical structure of quantum mechanics like the probability amplitudes, Born rule, commutation and uncertainty relations, probability density current, momentum operator, rules for including the scalar and vector potentials and antiparticles can be obtained from the probabilistic description of results of measurement of the space coordinates and time. Equations of motion of quantum mechanics, the Klein-Gordon equation, Schrodinger equation and Dirac equation are obtained from the requirement of the relativistic invariance of the space-time Fisher information. The limit case of the delta-like probability densities leads to the Hamilton-Jacobi equation of classical mechanics. Many particle systems and the postulates of quantum mechanics are also discussed.Comment: 21 page

The Political Interface of Financialisation and the Regulation of Mergers and Acquisitions in the EU

Contains fulltext : 111881.pdf (publisher's version ) (Closed access)Prior to the outbreak of the current global economic and financial crisis, the sheer number and volume of mergers and acquisitions set historically unprecedented records. A vast share of these transactions were undertaken by short-term oriented financial market actors, including private equity houses, hedge funds and other institutional investors. The article explains the adoption and ensuing adaptations of the supranational merger control at the level of the European Union (EU) on the basis of a critical political economy perspective. It argues that ever since its inception, EU merger control regulation primarily served to facilitate economic concentration, which was reinforced by a permissive stance of the European Commission. Alongside processes of financialisation and increased corporate reliance on financial market capitalisation, EU merger control underwent a substantive reform and additional adaptations, which in important ways sustained financial sector induced mergers.19 p

CAPITAL MOBILITY, DOMESTIC POLITICS, and FRENCH MONETARY DIPLOMACY

This article evaluates the role of increased capital mobility, sectoral interests, and domestic institutions in bringing about policy change in French capital markets. Capital mobility played an indirect role by making it more costly for French governments to pursue inflationary economic policies. But it was domestic politics, not capital mobility, that led governments to achieve lower inflation by stabilizing the exchange rate. The key domestic political factor was institutional change to regulatory practices, while financial markets reduced bank lending to industry and internationalized French finance, breaking the strong ties and comon monetary diplomacy interests of bankers, industralists, and policymakers, and thereby weaken the political priority of promoting domestic growth and industrial competitiveness.
