dc.description.abstract | A class of the Newell–Whitehead–Segel equations (also known as generalized Fisher equations and Newell–Whitehead equations) is studied with Lie and “nonclassical” symmetry points of view. The classifications of Lie reduction operators and of regular nonclassical reduction operators are performed. The set of admissible transformations (the equivalence groupoid) of the class is described exhaustively. The criterion of reducibility of variable coefficient Newell–Whitehead–Segel equations to their constant coefficient counterparts is derived. Wide families of exact solutions for such variable coefficient equations are constructed. | en |
