The collocation and least squares method on adaptive grids in a domain with a curvilinear boundary

A version of the grid-projection method for solving boundary problems for elliptic equations in a domain with a curvilinear boundary on the rectangular adaptive grid is presented. The method is tested on the equations with a small parameter at highest derivatives. Convergence of the method and the grid adaptability to the peculiarity of the solution are shown.
