The G&G Model: A Potential-Based Resolution of Fractional Governance Fields With Entropic Noise and Stochastic Control for Digital Regulation in Africa

International Journal of Differential Equations
Our paper introduces a mathematical governance model for digital regulation in Africa by extending the previous G&G model to capture digital propagation effects on social behavior.

Dynamic Mean-Variance Model with Borrowing Constraint under the Constant Elasticity of Variance Process

Journal of Applied Mathematics, 2013
This paper studies a continuous-time dynamic mean-variance portfolio selection problem with the constraint of a higher borrowing rate, in which stock price is governed by a constant elasticity of variance (CEV) process. Firstly, we apply Lagrange duality

Optimal investment models with vintage capital: Dynamic Programming approach [PDF]

The Dynamic Programming approach for a family of optimal investment models with vintage capital is here developed. The problem falls into the class of infinite horizon optimal control problems of PDE's with age structure that have been studied in various

Flat holography & holographic renormalization: scalar field

Journal of High Energy Physics
We adapt the Hamilton-Jacobi method of holographic renormalization to scalar field theories in Minkowski spacetime with scattering boundary conditions.

Non-SUSY DW’s in ISO(7) gauged supergravity

Journal of High Energy Physics
We consider 4D maximal ISO(7) gauged supergravity, which is known to arise from a consistent truncation of massive IIA supergravity on a six-sphere. Within its SU(3) invariant sector, the theory is known to possess eight AdS vacua, preserving various ...

Hamilton-Jacobi Equations [PDF]

, 2017
This thesis presents the theory of Hamilton-Jacobi equations. It is first shown how the equation is derived from the Lagrangian mechanics, then the traditional methods for searching for the solution are presented, where the Hopf-Lax formula along with ...

Optimal Impulsive Control and Stabilization of Dynamic Systems Based on Quasi-Variational Inequalities

Mathematics
In this paper, we investigate the optimal control problem regarding a class of dynamic systems, aiming to address the challenge of simultaneously ensuring cost minimization and system asymptotic stability. The theoretical framework proposed in this paper

Geometric Hamilton-Jacobi theory for nonholonomic dynamical systems [PDF]

, 2009
The geometric formulation of Hamilton--Jacobi theory for systems with nonholonomic constraints is developed, following the ideas of the authors in previous papers.

Hamilton-Jacobi approach to pre-big bang cosmology at long wavelengths

, 1999
We apply the long-wavelength approximation to the low-energy effective string action in the context of the Hamilton-Jacobi theory. The Hamilton-Jacobi equation for the effective string action is explicitly invariant under scale factor duality. We present
