On the boundary integral-equations for the crack opening displacement of flat cracks
The author considers the first kind boundary integral equations \(Du=f\) in a bounded smooth domain in the plane, where \(D\) is the hypersingular operator associated with the Helmholtz equation and the Lamé system, respectively. Regarding \(D\) is a pseudodifferential operator and computing its complete symbol, he proves a coerciveness estimate and a solvability result.
