Abstract
In this dissertation, we apply Lie theory to determine the one-parameter point transformations which leave complex-valued Korteweg-de Vries equations in- variant. The conserved vectors of the systems are constructed. We provide travelling wave reductions that lead to third-order ordinary differential equa- tions. These equations are highly nonlinear to solve directly, and therefore we first establish their first integrals. The latter is of second-order and facilitates the solution of the complex-valued system.
