Boundary Integral Equations on Contours with Peaks (Operator by Vladimir Maz'ya, Alexander Soloviev

By Vladimir Maz'ya, Alexander Soloviev

This e-book is a complete exposition of the idea of boundary quintessential equations for unmarried and double layer potentials on curves with external and inside cusps. 3 chapters disguise harmonic potentials, and the ultimate bankruptcy treats elastic potentials.
