Lie Symmetry Analysis of the Hopf Functional-Differential Equation
Lie Symmetry Analysis of the Hopf Functional-Differential Equation
In this paper, we extend the classical Lie symmetry analysis from partial differential equations to integro-differential equations with functional derivatives. We continue the work of Oberlack and Wacławczyk (2006, Arch. Mech. 58, 597), (2013, J. Math. Phys. 54, 072901), where the extended Lie symmetry analysis is performed in the Fourier …
