## Abstract The paper is devoted to the study of solutions to linear elliptic boundary value problems in domains depending smoothly on a small perturbation parameter. To this end we transform the boundary value problem onto a fixed reference domain and obtain a problem in a fixed domain but with di

The singularities near the crack tips of homogeneous materials are monotone of type r ฮฑ and r ฮฑ log ฮด r (depending on the boundary conditions along nonsmooth domains). However, the singularities around the interfacial cracks of the heterogeneous bimaterials are oscillatory of type r ฮฑ sin(ฮต log r ).
## Consider the Dirichlet boundary value problem ) u=0, on 0, where 0 is a bounded domain R N and \* 1 is the first eigenvalue of &2 in 0, under Dirichlet boundary conditions. Let . 1 be the corresponding eigenfunction. Such a resonance problem is easy to deal with if the potential G(x, u)= | u 0
