چکیده

The Banfi-Marchesini-Smye (BMS) equation accounts for non-global logarithms to all orders in perturbation theory the large-Nc approximation. We show that squared amplitudes emission of soft energy-ordered gluons are correctly embedded this equation, and explicitly verify they coincide with those derived our previous work limit up sixth order strong coupling. perform analytical calculations fourth specific hemisphere mass distribution e+ e- collisions, thus confirming semi-numerical results. solution BMS may be cast into a product an infinite number exponentials each which resums class Feynman diagrams manifest symmetry pattern, carry out computation first these exponentials.

Knots, Braids and Hedgehogs from the Eikonal Equation

The complex eikonal equation in the three space dimensions is considered. We show that apart from the recently found torus knots this equation can also generate other topological configurations with a non-trivial value of the π2(S 2) index: braided open strings as well as hedgehogs. In particular, cylindric strings i.e. string solutions located on a cylinder with a constant radius are found. Mo...

A kinetic eikonal equation

We analyse the linear kinetic transport equation with a BGK relaxation operator. We study the large scale hyperbolic limit (t, x) → (t/ε, x/ε). We derive a new type of limiting Hamilton-Jacobi equation, which is analogous to the classical eikonal equation derived from the heat equation with small diffusivity. We prove well-posedness of the phase problem and convergence towards the viscosity sol...

Knotted Configurations with Arbitrary Hopf Index from the Eikonal Equation

The complex eikonal equation in (3+1) dimensions is investigated. It is shown that this equation generates many multi-knot configurations with an arbitrary value of the Hopf index. In general, these eikonal knots do not have the toroidal symmetry. For example, a solution with topology of the trefoil knot is found. Moreover, we show that the eikonal knots provide an analytical framework in which...

Stripe Patterns and the Eikonal Equation

We study a new formulation for the eikonal equation |∇u| = 1 on a bounded subset of R. Considering a field P of orthogonal projections onto 1-dimensional subspaces, with divP ∈ L, we prove existence and uniqueness for solutions of the equation P divP = 0. We give a geometric description, comparable with the classical case, and we prove that such solutions exist only if the domain is a tubular n...

Wavefronts and solutions of the eikonal equation

S U M M A R Y In this paper, several methods for the solution of the eikonal equation are investigated. Using the method of characteristics, traveltimes are computed along rays. Approximate solutions of the eikonal equation can also be obtained. From Fermat’s principle, first-order changes in the traveltime can be found by integrating along initial ray trajectories. Alternatively, linearized ra...
