... The function f (x) = x − g(x) is continuous on [a, b] and crosses the axis: f (a) = a − g(a) < 0 < b − g(b) = f (b). Hence, there exists at least one zero, u, of f (that is, a fixed point of g) in [a, b]. Assume also that g(v) = v 6= u. Then 0 < |u − v| = |g(u) − g(v)| < λ|u − v| < |u − v|, a contra ...

Finite element method
In mathematics, the finite element method (FEM) is a numerical technique for finding approximate solutions to boundary value problems for partial differential equations. It uses subdivision of a whole problem domain into simpler parts, called finite elements, and variational methods from the calculus of variations to solve the problem by minimizing an associated error function. Analogous to the idea that connecting many tiny straight lines can approximate a larger circle, FEM encompasses methods for connecting many simple element equations over many small subdomains, named finite elements, to approximate a more complex equation over a larger domain.
