The Shigesada-Kawasaki-Teramoto model: conditional symmetries, exact solutions and their properties. (English) Zbl 1518.35032
Summary: We study a simplification of the well-known Shigesada-Kawasaki-Teramoto model, which consists of two nonlinear reaction-diffusion equations with cross-diffusion. A complete set of \(Q\)-conditional (nonclassical) symmetries is derived using an algorithm adopted for the construction of conditional symmetries. The symmetries obtained are applied for finding a wide range of exact solutions, possible biological interpretation of some of which being presented. Moreover, an alternative application of the simplified model related to the polymerization process is suggested and exact solutions are found in this case as well.
