Mobilising Judicial Voices: How and Why National Courts Express Their Opinions in the Preliminary Reference Procedure – A Case Study of Czechia

JCMS: Journal of Common Market Studies, EarlyView.
Abstract This article interrogates the national courts' pre‐emptive opinions expressed in the Article 267 of the Treaty on the Functioning of the European Union preliminary reference procedure from both theoretical and analytical angles. First, we theorise about the variety of factors influencing national courts' decision to supply the Court of Justice

On the slow roll expansion of one-field cosmological models

Nuclear Physics B
We study the infrared scale expansion of single field cosmological models using the Hamilton-Jacobi formalism, showing that its specialization at unit scale parameter recovers the slow roll expansion. In particular, we show that the latter coincides with

The Equivalence Postulate of Quantum Mechanics, Dark Energy, and the Intrinsic Curvature of Elementary Particles

Advances in High Energy Physics, 2013
The equivalence postulate of quantum mechanics offers an axiomatic approach to quantum field theories and quantum gravity. The equivalence hypothesis can be viewed as adaptation of the classical Hamilton-Jacobi formalism to quantum mechanics.

Hamiltonian approach to GR – Part 1: covariant theory of classical gravity

European Physical Journal C: Particles and Fields, 2017
A challenging issue in General Relativity concerns the determination of the manifestly covariant continuum Hamiltonian structure underlying the Einstein field equations and the related formulation of the corresponding covariant Hamilton–Jacobi theory ...

Reputation Management: Exploring the Commission's Communication on Innovation

JCMS: Journal of Common Market Studies, EarlyView.
Abstract The cultivation and maintenance of reputation through strategic communication are key to the Commission's standing, as reputation constitutes a critical resource for the survival of institutional entities. These considerations are particularly salient in areas related to shared and supporting competences, where demonstrating commitment to core

Robust Mean–Variance Portfolio Optimization: Mean–Variance–Variance Criterion Versus Mean–Variance–Standard Deviation Criterion

Mathematical Finance, EarlyView.
ABSTRACT We study a dynamic portfolio optimization problem under the mean–variance–variance (M‐V‐V) criterion proposed by Maccheroni et al. It is an analogue of the Arrow–Pratt approximation to the well‐known smooth ambiguity model. Under the standard Black–Scholes framework, we derive fully explicit equilibrium investment strategies in which a DM's ...

A characterization of the Jacobi logarithms of a finite field

Discrete Mathematics, 2001
The special properties which an orthomorphism or near orthomorphism of a cyclic group must have if it is to define a finite field instead of a nonassociative cyclic neofield are determined.

Market Making With Fads, Informed, and Uninformed Traders

Mathematical Finance, EarlyView.
ABSTRACT We characterize the solution to a continuous‐time optimal liquidity provision problem in a market populated by informed and uninformed traders. In our model, the asset price exhibits fads —these are short‐term deviations from the fundamental value of the asset.

How Can Law Be Robust in the Face of Heightened Societal Turbulence?

Regulation &Governance, EarlyView.
ABSTRACT Taking its cue from the growing frequency of disruptive crises, new research argues that crisis‐induced turbulence calls for robust governance based on adaptation and innovation. While law plays a key role in the effort of governments to govern robustly, the robustness of law has received scant regard.

Arbitrary Lagrangian–Eulerian Formulation in a Rotating Frame to Model Friction Spinning

Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 4, December 2026.
ABSTRACT Friction spinning is a metal forming process that can be used to manufacture various shapes by rotating a metallic workpiece relative to a blunt tool. When used as a hot metal forming process, the relative velocity between workpiece and tool is increased until substantial heat is generated due to friction.
