Modeling Geoid and Dynamic Topography From Tomography‐Based Thermo‐Chemical Mantle Convection

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 2, February 2026.
Abstract Mantle convection causes the most important contribution to the geoid and dynamic topography. With mantle density inferred from high‐resolution tomography models and numerical methods solving the governing equations of viscous mantle flow, the modeled geoid can fit the observations well.

Nonexistence of self-similar singularities for the 3D incompressible Euler equations

, 2006
We prove that there exists no self-similar finite time blowing up solution to the 3D incompressible Euler equations. By similar method we also show nonexistence of self-similar blowing up solutions to the divergence-free transport equation in $\Bbb R^n$.

2D Voigt Boussinesq Equations

Journal of Mathematical Fluid Mechanics
We consider a critical conservative Voigt regularization of the 2D incompressible Boussinesq system on the torus. We prove the existence and uniqueness of global smooth solutions and their convergence in the smooth regime to the Boussinesq solution when the regularizations are removed. We also consider a range of mixed (subcritical-supercritical) Voigt

Persistent Ocean‐Shelf Transport Across the North West European Shelf Edge

Journal of Geophysical Research: Oceans, Volume 131, Issue 2, February 2026.
Abstract Transport mechanisms between the deep ocean and adjacent continental shelf seas play an important role in the spatial distribution of nutrient delivery to the coastal ocean and in the temporal variability of shelf biogeochemical processes. Along the North West European Shelf (NWES) edge, nutrient‐rich waters of oceanic origin are found below ...

A fast preliminary estimation model for transoceanic tsunami propagation [PDF]

Geofísica Internacional, 2000
A simplified one-dimensional method is proposed to estimate the height of the leading wave of transoceanic tsunamis by means of a directivity function applied to the one-dimensional finite difference model based on the shallow water equations.

New Multiple Solution to the Boussinesq Equation and the Burgers-Like Equation

Journal of Applied Mathematics, 2013
By considering an improved tanh function method, we found some exact solutions of Boussinesq and Burgers-like equations. The main idea of this method is to take full advantage of the Riccati equation which has more new solutions.

The Impact of Orogenic Inheritance on Rifted Margin Formation

Tectonics, Volume 45, Issue 2, February 2026.
Abstract Many rifted margins form within pre‐existing orogenic belts, emphasizing the significance of structural, thermal, and compositional inheritance in shaping rift dynamics. However, a key unresolved question is how these different types of orogenic inheritance individually influence rift evolution.

Analytical smoothing effect of solution for the boussinesq equations

, 2017
In this paper, we study the analytical smoothing effect of Cauchy problem for the incompressible Boussinesq equations. Precisely, we use the Fourier method to prove that the Sobolev H 1-solution to the incompressible Boussinesq equations in periodic ...

Elliptic Solitons and Groebner Bases

, 2002
We consider the solution of spectral problems with elliptic coefficients in the framework of the Hermite ansatz. We show that the search for exactly solvable potentials and their spectral characteristics is reduced to a system of polynomial equations ...
