      Enhanced group classification of Benjamin–Bona–Mahony–Burgers equations 

      Vaneeva, Olena O.; Pošta, Severin; Sophocleous, Christodoulos (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. ...

      Lie group analysis of two-dimensional variable-coefficient Burgers equation 

      Ivanova, Nataliya M.; Sophocleous, Christodoulos; Tracinà, Rita (2010)
      The modern group analysis of differential equations is used to study a class of two-dimensional variable coefficient Burgers equations. The group classification of this class is performed. Equivalence transformations are ...

      Lie symmetries of generalized Burgers equations: application to boundary-value problems 

      Vaneeva, Olena O.; Sophocleous, Christodoulos; Leach, Peter G. L. (2015)
      There exist several approaches exploiting Lie symmetries in the reduction of boundary-value problems for partial differential equations modelling real-world phenomena to those problems for ordinary differential equations. ...

      Numerical similarity reductions of the (1+3)-dimensional Burgers equation 

      Christou, Marios Andreas; Sophocleous, Christodoulos (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 ...
