An Exact Logistic Solution of a Fifth-Order Equation in Five Variables
Year: 2026
Type: article
Abstract: An explicit fifth-order nonlinear equation in one time and four space variables admits a logistic travelling-wave solution. The fifth directional derivative is factored exactly into elementary polynomials. Direct substitution verifies the equation without an assertion about well-posedness or the general solution set.
