Abstract:
The paper is devoted to the Cauchy problem for a differential equation with a small parameter when using a Fredholm operator in a Banach space with a certain method. The investigated effect of this parameter. The solution is in the form of an asymptotic expansion. When solving the problems of using the cascade decomposition method for equations, which allows us to split the equation into equations in subspaces.
Keywords:differential equation, asymptotic solution, small parameter, perturbation in the right-hand side, Fredholm operator, boundary layer phenomenon.
