Model Ambiguity versus Model Misspecification in Dynamic Portfolio Choice

The Journal of Finance, EarlyView.
ABSTRACT We study aversion to model ambiguity and misspecification in dynamic portfolio choice. Risk‐averse investors (relative risk aversion γ>1$\gamma > 1$) fear return persistence, while risk‐tolerant investors (0<γ<1$0<\gamma <1$) fear mean reversion, when confronting model misspecification concerns of identically and independently distributed (IID)

The complete solution of the Hamilton-Jacobi equation in Quantum Mechanics

, 1996
An ordinary unambiguous integral representation for the finite propagator of a quantum system is found by starting of a privileged skeletonization of the functional action in phase space, provided by the complete solution of the Hamilton-Jacobi equation.

Discrete Hamilton-Jacobi Theory

, 2011
We develop a discrete analogue of Hamilton-Jacobi theory in the framework of discrete Hamiltonian mechanics. The resulting discrete Hamilton-Jacobi equation is discrete only in time.

Unified Analysis of Fermionic Tunneling, Barrow‐Exponential Entropy Corrections, and Plasma Lensing in Carrollian Reissner‐Nordström Spacetime

Annalen der Physik, Volume 538, Issue 3, March 2026.
Carrollian Reissner‐Nordström black holes are investigated through fermionic tunneling, entropy‐corrected thermodynamics, and plasma‐modified gravitational lensing. The generalized uncertainty principle introduces minimal‐length corrections to the Hawking temperature, while the combined Barrow‐Exponential entropy reveals smooth thermodynamic crossovers

Supermarket Settings and Consumer Behavior: A Systematic Mapping Review and Future Research Avenues

International Journal of Consumer Studies, Volume 50, Issue 2, March 2026.
ABSTRACT Supermarkets and related environments are not just places to buy groceries; they are complex environments filled with diverse stimuli that shape consumer behavior and decision‐making processes. Despite their increasing use as study settings, there remains a lack of comprehensive understanding regarding which supermarket‐type settings are ...

Converting Classical Theories to Quantum Theories by Solutions of the Hamilton-Jacobi Equation

, 2012
By employing special solutions of the Hamilton-Jacobi equation and tools from lattice theories, we suggest an approach to convert classical theories to quantum theories for mechanics and field theories.

A General Dynamic Programming Approach to the Optimal Water Storage Management for Irrigation

Mathematical Methods in the Applied Sciences, Volume 49, Issue 3, Page 1987-1997, February 2026.
ABSTRACT This paper proposes a dynamic programming approach targeted to solve a natural resource problem of water storage management for irrigation in an environmentally and socially sustainable way. The problem we address in our formulation, focusing on the control of water storage in tanks, is based on assumptions that are less restrictive than those

Some Aspects of Modality in Analytical Mechanics [PDF]

, 2002
This paper discusses some of the modal involvements of analytical mechanics. I first review the elementary aspects of the Lagrangian, Hamiltonian and Hamilton-Jacobi approaches. I then discuss two modal involvements; both are related to David Lewis' work
