Global branches of multi-bump periodic solutions of the Swift-Hohenberg equation. (English) Zbl 0983.34032
The authors present new families of global branches of single- and multipump periodic solutions to the fourth-order equation \[ d^4u/dx^4+qd^2u/dx^2+u^3-u=0, q\in\mathbb{R}, \] arising in problems of pattern formation. They view the problem as a nonlinear eigenvalue problem with \(q\) as eigenvalue parameter. By means of analytical as well as numerical methods, branches of periodic solutions are investigated, both locally and globally.
