Abstract
The group classification problem for the class of (1+1)-dimensional linear rth order evolution equations is solved for arbitrary values of r>2. It is shown that a related maximally gauged class of homogeneous linear evolution equations is uniformly semi-normalized with respect to linear superposition of solutions and hence the complete group classification can be obtained using the algebraic method. We also compute exact solutions for equations from the class under consideration using Lie reduction and its specific generalizations for linear equations.
