Singular integrals and fractional powers of operators

open access: yes, 1971
Recently R. Wheeden studied a class of singular integral operators, the hypersingular integrals, as operators from L p α ( H ) L_p^\alpha (H) to

A posteriori error estimates for boundary element methods

open access: yes, 1995
This paper deals with a general framework for a posteriori error estimates in boundary element methods which is specified for three examples, namely Symm’s integral equation, an integral equation with a hypersingular operator, and a boundary integral ...

On an approximate solution of integral equations with a strong singularity in the kernel

open access: yes
The author considers a hypersingular integral equation over the interval perturbed by an integral operator with smooth kernel function. Multiplying the integral operator by invertible operators, she obtains two equivalent equations, a Fredholm equation ...

A Posteriori Error Estimates for hp-Boundary Element Methods

open access: yes, 1995
This paper presents a posteriori error estimates for the hp-version of the boundary element method. We discuss two first kind integral operator equations, namely Symm's integral equation and the integral equation with a hypersingular operator.
