Stripe patterns and a projection-valued formulation of the eikonal equation
, 2012 We describe recent work on striped patterns in a system of block copolymers. A by-product of the characterization of such patterns is a new formulation of the eikonal equation.

Relativistic eikonal expansion. [Scalar-scalar theory]
, 1977 The generalized ladder series of Feynman diagrams for scattering of two particles by scalar meson exchange is expanded, using functional methods, to obtain the relativistic eikonal approximation and the next two terms of an expansion about the eikonal ...

Applications of Disaffinity Vectors to Certain Riemannian Manifolds
MathematicsA disaffinity vector on a Riemannian manifold is a vector field whose affinity tensor vanishes. In this paper, we prove that every disaffinity vector on a compact Riemannian manifold is an incompressible vector field.

Prestack first-break traveltime tomography using the double-square-root eikonal equation
, 2012 Traveltime tomography with shot-based eikonal equation fixes shot positions then relies on inversion to resolve any contradicting information between independent shots and achieve a possible cost-function minimum.

We present a numerical scheme based on the Fast Marching Method to solve the eikonal equation in 3D for a direct electromagnetic problem. The eikonal equation is discretized using a Cartesian grid and a second order Godunov upwind finite differences is ...

Not all that is β 0 is β-function: the DGLAP resummation and the running coupling in NLO JIMWLK
Journal of High Energy PhysicsWe reanalyze the origin of the large transverse logarithms associated with the QCD one loop β function coefficient in the NLO JIMWLK Hamiltonian. We show that some of these terms are not associated with the running of the QCD coupling constant but rather
