Localized Boundary Knot Method for Solving Two-Dimensional Laplace and Bi-Harmonic Equations

Mathematics, 2020
In this paper, a localized boundary knot method is proposed, based on the local concept in the localized method of fundamental solutions. The localized boundary knot method is formed by combining the classical boundary knot method and the localization ...

Probing partially localized supergravity background of fundamental string ending on Dp-brane [PDF]

, 1999
We study the dynamics of the probe fundamental string in the field background of the partially localized supergravity solution for the fundamental string ending on Dp-brane.

Partially Localized Intersecting BPS Branes [PDF]

, 1999
We present the explicit forms of supergravity solutions for the various intersecting two BPS branes in eleven and ten dimensions, where one brane is localized at the delocalized other brane.

Discrete surface solitons in two dimensions [PDF]

, 2006
We investigate fundamental localized modes in 2D lattices with an edge (surface). Interaction with the edge expands the stability area for ordinary solitons, and induces a difference between perpendicular and parallel dipoles; on the contrary, lattice ...

Higher-order nonlinear modes and bifurcation phenomena due to degenerate parametric four-wave mixing [PDF]

, 2000
We demonstrate that weak parametric interaction of a fundamental beam with its third harmonic field in Kerr media gives rise to a rich variety of families of non-fundamental (multi-humped) solitary waves.

Localized boundary-domain integral formulations for problems with variable coefficients [PDF]

, 2002
Specially constructed localized parametrixes are used in this paper instead of a fundamental solution to reduce a boundary value problem with variable coefficients to a localized boundary-domain integral or integro-differential equation (LBDIE or LBDIDE).

Time-Reversal of Nonlinear Waves - Applicability and Limitations [PDF]

, 2016
Time-reversal (TR) refocusing of waves is one of fundamental principles in wave physics. Using the TR approach, "Time-reversal mirrors" can physically create a time-reversed wave that exactly refocus back, in space and time, to its original source ...
