A note on the extension of the polar decomposition for the multidimensional Burgers equation
arXiv:nlin/0205049 · doi:10.1103/PhysRevE.67.067301
Abstract
It is shown that the generalizations to more than one space dimension of the pole decomposition for the Burgers equation with finite viscosity and no force are of the form u = -2 viscosity grad log P, where the P's are explicitly known algebraic (or trigonometric) polynomials in the space variables with polynomial (or exponential) dependence on time. Such solutions have polar singularities on complex algebraic varieties.
