General interface problems. II. (English) Zbl 0824.35015

This is a continuation of the authors’ previous paper [ibid. 395-429 (1994) (see the preceding review)]. The authors prove the regularity and the asymptotics of solutions in usual Sobolev spaces for nonconstant coefficients operators. The stabilization procedure is proposed when unstable decompositions appear near a critical angle.
