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
