Exact solutions for hydrodynamic interactions of two squirming spheres [PDF]

, 2016
We provide exact solutions of the Stokes equations for a squirming sphere close to a no-slip surface, both planar and spherical, and for the interactions between two squirmers, in three dimensions.

Exact Solutions in Modified Gravity Models

Entropy, 2012
We review the exact solutions in modified gravity. It is one of the main problems of mathematical physics for the gravity theory. One can obtain an exact solution if the field equations reduce to a system of ordinary differential equations. In this paper

Approach to first-order exact solutions of the Ablowitz-Ladik equation [PDF]

, 2011
We derive exact solutions of the Ablowitz-Ladik (A-L) equation using a special ansatz that linearly relates the real and imaginary parts of the complex function.

Exact solutions of closed string theory [PDF]

, 1995
We review explicitly known exact $D=4$ solutions with Minkowski signature in closed bosonic string theory. Classical string solutions with space-time interpretation are represented by conformal sigma models.

Exact Solutions for Nonclassical Stefan Problems

International Journal of Differential Equations, 2010
We consider one-phase nonclassical unidimensional Stefan problems for a source function F which depends on the heat flux, or the temperature on the fixed face x=0.

Exact multi-membrane solutions in AdS_7 [PDF]

, 2001
We study the properties of an exact multi-membrane solution in seven-dimensional maximal SO(5)-gauged supergravity. Unlike previously known multi-centered solutions, the present one is asymptotically anti-de Sitter.

Exact solutions for Weyl fermions with gravity [PDF]

, 2015
We consider the single-handed spinor field in interaction with its own gravitational field described by the set of field equations given by Weyl field equations written in terms of derivatives that are covariant with respect to the gravitational ...

Two-mode coupled Burgers equation: Multiple-kink solutions and other exact solutions

Alexandria Engineering Journal, 2018
In this paper, we establish a new two-mode coupled Burgers equation (TMCBE). The necessary conditions that make the multiple kink solutions and the multiple singular kink solutions to TMCBE exist are founded using the simplified bilinear method. Moreover,
