"Residual-based a posteriori error estimate for hypersingular equation on surfaces";
Numerische Mathematik, 97 (2004), 3; S. 397 - 426.

Kurzfassung englisch:
The hypersingular integral equation of the first kind equivalently
describes screen and Neumann problems on an open surface piece. The
paper establishes a computable upper error bound for its Galerkin
approximation and so motivates adaptive mesh refining algorithms.
Numerical experiments for triangular elements on a screen provide
empirical evidence of the superiority of adapted over uniform
mesh-refining. The numerical realisation requires the evaluation of
the hypersingular integral operator at a source point; this and\
other details on the algorithm are included.
