| Abstract: |
| In this paper,the nonlinear singular perturbation problem for the evolution equations is studied.The outer solution and corrective terms of the pointed,boundary and initial layers for the solution are constructed.By using the fixed point theorem,the uniformly validity of solution to the problem ia proved and the results of the study for the singular perturbation with two parameters is extended. |
| Key words: pointed layer singular perturbation evolution equation |
