Stationary Coexistence of Hexagons and Rolls via Rigorous Computations

Stationary Coexistence of Hexagons and Rolls via Rigorous Computations

In this work we introduce a rigorous computational method for finding heteroclinic solutions of a system of two second order differential equations. These solutions correspond to standing waves between rolls and hexagonal patterns of a two-dimensional pattern formation PDE model. After reformulating the problem as a projected boundary value problem …
