A Singular Problem,In this chapter we shall study the numerical solution of a singular parabolic equation in one space dimension which arises after reduction by polar coordinates of a radially symmetric parabolic equation in three space dimensions. We shall analyze and compare finite element discretizations based on two different variational formulations.

In order not to have to account for possible exponential growth of stability constants and error bounds we restrict our consid

Our approach is to first study the discretization with respect to time of an abstract parabolic equation in a Hilbert space setting by using rational approximations of the expon

Kathleen Lynch,Maureen Lyons,Sara Cantillonuse the semigroup approach and represent the time stepping operator as a Dunford-Taylor integral in the complex plane, which will allow us to treat more general elliptic operators than in the previous chapter. For the purpose of including also application to maximum-norm estimates with respect to a
