Enhanced group classification of Benjamin–Bona–Mahony–Burgers equations
(2017)A class of the Benjamin–Bona–Mahony–Burgers (BBMB) equations with time-dependent coefficients is investigated with the Lie symmetry point of view. The set of admissible transformations of the class is described exhaustively. ...

Group analysis of (2 + 1)- and (3 + 1)-dimensional diffusion-convection equations
(2008)We perform the complete Lie group classification of a (2 + 1)- and a (3 + 1)-dimensional classes of non-linear diffusion-convection equations. This classification generalizes and completes existing results in the literature. ...

Numerical similarity reductions of the (1+3)-dimensional Burgers equation
(2011)We consider the (1+3)-dimensional Burgers equation ut = u xx + uyy + uzz + uux which has considerable interest in mathematical physics. Lie symmetries are used to reduce it to certain ordinary differential equations. We ...

Similarity reductions of the (1 + 3)-dimensional Burgers equation
(2009)We consider the (1 + 3)-dimensional Burgers equation ut = uxx + uyy + uzz + uux which has considerable interest in mathematical physics. We complete the list of similarity reductions that are obtained from the Lie symmetries ...
