First we present an abstract result of implicit function theorem type. Then we apply this to singularly perturbed boundary value problems of the type $$ \begin{array}{l} \varepsilon ^2\left( a(x)u'(x)\right) '+ b(x,u(x),\varepsilon )= 0, \quad x \in (0,1),\\ u(0)=u'(1)=0, \end{array} $$which are spatially nonsmooth, i.e. such thatis allowed to be discontinuous and thatis allowed to be non-differentiable. We show existence and local uniqueness of boundary layer solutionsclose to zeroth order approximate boundary layer solutions, i.e. such thatfor. These results are straightforward generalizations of those which are known for spatially smooth problems. But the rate of convergence, which is known for spatially smooth problems, is not true anymore for spatially nonsmooth problems, in general.
