The two-dimensional eikonal equation

Siberian Mathematical Journal, 2006
Summary: We study the two-dimensional eikonal equation \(\psi_x^2+ \psi_y^2=1/v^2(x,y)\). We carry out the group analysis of the equation, establish a connection between the group properties and geometric characteristics of the Riemannian space with the metric \(ds^2=[dx^2+dy^2]/v^2(x,y)\).

Viscosity Solutions of the Eikonal Equation on the Wasserstein Space

Applied Mathematics and Optimization, 2023
Dynamic programming equations for mean field control problems with a separable structure are Eikonal type equations on the Wasserstein space. Standard differentiation using linear derivatives yield a direct extension of the classical viscosity theory. We

Eikonal-equation-based characteristic reflection traveltime tomography

Geophysics, 2023
Automatically picking reflection traveltimes from the pre-stack shot gathers and positioning and updating the reflector depths during inversion are challenging in conventional Eikonal-equation-based adjoint state reflection traveltime tomography methods.
