Linearized perturbations

When a nonlinear system of partial differential equations is too hard to treat analytically in a fully nonlinear way an option for obtaining some information is to linearize about a known solution. This is common in the study of self-gravitating systems but there are some particular difficulties associated with the Einstein equations which create obstacles to progress. I am interested in overcoming these and this is the subject of a recent paper together with Paul Allen.
