Aldhlki T. Jassim Dep. of MathsCollege of Basic Education University of Mustansirya, Baghdad, Iraq talatjassim10@yahoo.com Abstract In this paper, we discuss the reduction of IBVP by using the definition of Bluman or Ibragimov. Moreover, some examples that explain this definition for linear and nonlinear heat equation, are given. Next, we will give some restrictions on the Lie symmetry, which make the initial-boundary conditions are invariant. Finally, we find an initial condition which…

Although the Blasius flow solves a nonlinear partial differential equation (PDE), Toepfer successfully computed highly accurate numerical solutions in 1912, and it is shown that PDE numerical studies were possible even in the precomputer age.
