Existence and Orbital Stability of Standing‐Wave Solutions of the Nonlinear Logarithmic Schrödinger Equation On a Tadpole Graph

Studies in Applied Mathematics, Volume 155, Issue 1, July 2025.
ABSTRACT This work aims to study some dynamical aspects of the nonlinear logarithmic Schrödinger equation (NLS‐log) on a tadpole graph, namely, a graph consisting of a circle with a half‐line attached at a single vertex. By considering Neumann–Kirchhoff boundary conditions at the junction, we show the existence and the orbital stability of standing ...

Efficient computation of high index Sturm-Liouville eigenvalues for problems in physics

, 2008
Finding the eigenvalues of a Sturm-Liouville problem can be a computationally challenging task, especially when a large set of eigenvalues is computed, or just when particularly large eigenvalues are sought.

Energetics of (Super)Tidal Baroclinic Modes in a Realistically Forced Global Ocean Simulation

Journal of Geophysical Research: Oceans, Volume 130, Issue 6, June 2025.
Abstract In this study, we diagnose the spatial variability in the energetics of tidally generated diurnal, semidiurnal, and supertidal (>2.5 ${ >} 2.5$ cycles per day) internal wave vertical modes (up to mode 6) in a 30‐day forward global ocean model simulation with a 4‐km grid spacing and 41 layers.

Variable-step finite difference schemes for the solution of Sturm-Liouville problems

, 2014
We discuss the solution of regular and singular Sturm-Liouville problems by means of High Order Finite Difference Schemes. We describe a code to define a discrete problem and its numerical solution by means of linear algebra techniques.

Phase‐Locked Internal‐Wave Triads Observed in the Izu‐Ogasawara Ridge: Implications for Interplay Between Tides and Winds

Journal of Geophysical Research: Oceans, Volume 130, Issue 6, June 2025.
Abstract The Ogasawara subregion of the Izu‐Ogasawara‐Mariana arc system in the western North Pacific is recognized as one of the most notable hotspots for thermocline turbulent mixing. Although parametric subharmonic instability (PSI) is generally considered a primary driver of enhanced turbulence by facilitating energy transfer from low‐mode ...

Improved Theoretical Estimates of the Zonal Propagation of Global Nonlinear Mesoscale Eddies

Journal of Geophysical Research: Oceans, Volume 130, Issue 6, June 2025.
Abstract Mesoscale eddies are essential for transport and mixing processes in the global ocean, with their characteristic westward propagation being a significant finding from the satellite altimetry era. Traditional predictions of their zonal propagation rely on the theoretical phase speed of long baroclinic Rossby waves; however, this approach is ...

Fundamental Results of Conformable Sturm-Liouville Eigenvalue Problems

Complexity, 2017
We suggest a regular fractional generalization of the well-known Sturm-Liouville eigenvalue problems. The suggested model consists of a fractional generalization of the Sturm-Liouville operator using conformable derivative and with natural boundary ...
