This monograph focuses on the mathematical and numerical analysis of simplicial partitions and the finite element method. This active area of research has become an essential part of physics and engineering, for example in the study of problems involving heat conduction, linear elasticity, semiconductors, Maxwell's equations, Einstein's equations and magnetic and gravitational fields.
These problems require the simulation of various phenomena and physical fields over complicated structures in three (and higher) dimensions. Since not all structures can be decomposed into simpler objects like d-dimensional rectangular blocks, simplicial partitions are important. In this book an emphasis is placed on angle conditions guaranteeing the convergence of the finite element method for elliptic PDEs with given boundary conditions. 
It is aimed at a general mathematical audience who is assumed to be familiar with only a few basic resultsfrom linear algebra, geometry, and mathematical and numerical analysis. 

Provides an accessible introduction to the finite element method (FEM), requiring only minimal prerequisites Emphasizes angle conditions for FEM convergence for elliptic PDEs with boundary conditions Presents 0/1-simplicial partitions of higher-dimensional unit cubes and maximally symmetric manifolds
