We consider a domain decomposition method for computing approximations to the conformal module m(Q) of Q in cases where Q is ‘long’ or, equivalently, m(Q) is ‘large’.

This method is based on decomposing the original quadrilateral Q into two or more component quadrilaterals Q 1, Q 2, and then approximating m (Q) by the sum ∑ j m. This paper contains a study of a domain decomposition method (DDM) for computing the conformal modules of long quadrilaterals.

The method involves decomposing the original quadrilateral Q into two or more component quadrilaterals Qj, j = 1, and then approxi- mating m(Q) by the sum Cm(Qj> of the conformal modules of the component.
