We consider a symmetric boundary integral formulation |
|
associated with a mixed boundary value problem defined on |
|
a domain Omega is an element of the set of real |
|
numbers(2) with piecewise smooth boundary Gamma. We |
|
assume that Omega is mapped onto itself by a finite group |
|
G of congruences having at least two distinct elements. |
|
Hence, we can decompose the related symmetric Galerkin |
|
BEM problem into independent subproblems of reduced |
|
dimension with respect to the complete one. Shape |
|
functions for each subproblem can be obtained from |
|
classical BEM basis, ordered as a vector, applying |
|
suitable restriction matrices constructed starting from |
|
group representation theory. |
