On the numerical solution of a nonlinear integral equation of Prandtl's type

open access: yes, 2005
: We discuss solvability properties of a nonlinear hypersingular integral equation of Prandtl’s type using monotonicity arguments together with different collocation iteration schemes for the numerical solution of such ...

Adaptive Mesh-Refinement for a Hypersingular Integral Equation in 2D

open access: yes, 2009
The 2D Laplace equation with Neumann boundary conditions can equivalently be stated as a first-kind integral equation $Wu = F$ with hypersingular integral operator $W$ and certain right-hand side $F$.

Integral equation methods for scattering from an impedance crack

open access: yes, 2003
For the scattering problem for time-harmonic waves from an impedance crack in two dimensions, we give a uniqueness and existence analysis via a combined single- and double-layer potential approach in a Hölder space setting leading to a system of integral

On the Uniform Boundedness of a Class of Hypersingular Integral Operators on the Hardy Space

open access: yesTamkang Journal of Mathematics
For a class of hypersingular integral operators, we establish optimal uniform bounds for their norms on the Hardy space $H^1(\R)$. Our results extend the classical result of Fefferman-Stein for the phase function $1/y$ to phase functions of the form $1/P(y)$ where $P$ is an arbitrary real polynomial.
