Linear and nonlinear reaction—diffusion problems

It is well known that the following e-explicit bound for all a: £ ft is valid for the derivatives of the solution of a typical problem in Problem Class 10.1

where C is a constant independent of e. This shows that, in general, regular boundary layers of width 0(y/e) appear at each boundary point x = 0 and x — 1.
