On Lagrangians with Reduced-Order Euler-Lagrange Equations [PDF]
Symmetry, Integrability and Geometry: Methods and Applications, 2018 If a Lagrangian defining a variational problem has order $k$ then its Euler-Lagrange equations generically have order $2k$. This paper considers the case where the Euler-Lagrange equations have order strictly less than $2k$, and shows that in such a case the Lagrangian must be a polynomial in the highest-order derivative variables, with a specific ...

Primal SPH Solver for Strongly Coupled Multiphase Simulations with High Density Ratios
Computer Graphics Forum, EarlyView.Abstract In recent years, the Smoothed Particle Hydrodynamics (SPH) approach has been increasingly used for multiphase simulations involving interactions between diverse materials. A critical component of an SPH simulator is the pressure solver, which not only facilitates the simulation of compressible or incompressible fluids but also handles contact ...

Image Restoration using a Nonlinear Second-order Parabolic PDE-based Scheme
Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2017 A novel anisotropic diffusion-based image denoising and restoration approach is proposed in this paper. A variational model for image restoration is introduced first, then the corresponding Euler-Lagrange equation being determined.

Monetary Policy When Preferences Are Quasi‐Hyperbolic
Journal of Money, Credit and Banking, EarlyView.Abstract We study discretionary monetary policy in an economy where economic agents have quasi‐hyperbolic discounting. We demonstrate that a benevolent central bank is able to keep inflation under control for a wide range of discount factors. If the central bank, however, does not adopt the household's time preferences and tries to discourage early ...

Monetary and Macroprudential Policies under Dollar‐Denominated Foreign Debt
Journal of Money, Credit and Banking, EarlyView.Abstract This paper studies monetary and macroprudential policies in a small open economy that borrows from abroad in foreign currency. The model features a novel mechanism in which exchange rate depreciation triggered by a borrowing constraint is amplified through balance of payments adjustments, increasing the real burden of foreign debt and causing ...

Deformation minimal bending of compact manifolds: case of simple closed curves [PDF]
Opuscula Mathematica, 2008 The problem of minimal distortion bending of smooth compact embedded connected Riemannian \(n\)-manifolds \(M\) and \(N\) without boundary is made precise by defining a deformation energy functional \(\Phi\) on the set of diffeomorphisms \(\text{Diff}(M ...

Policy Biases in a Model with Labor‐Market Frictions
Journal of Money, Credit and Banking, EarlyView.Abstract We develop a model with labor‐market matching frictions that is subject to a range of shocks, including shocks to matching efficiency and bargaining power, and use the model to examine how monetary policy should respond to such shocks. We show that optimal monetary policy responds effectively to these shocks, producing economic outcomes that ...
