关于最新的边界元快速算法的专著，提出了一种代数方法来加快边界元方程组的求解。值得一看。(Boundary Element Methods (BEM) play an important role in modern numer- ical computations in the applied and engineering sciences. Such algorithms are often more convenient than the traditional Finite Element Method (FEM), since the corresponding equations are formulated on the boundary, and, there- fore, a signifi cant reduction of dimensionality takes place. Especially when the physical description of the problem leads to an unbounded domain, traditional methods like FEM become unalluring)
