We investigate certain pure injective modules over generalised Weyl algebras. We consider pure injective hulls of finite length modules, the elementary duals of these, torsionfree pure injective modules, and the closure in the Ziegler spectrum of the category of finite length modules supported on a
For simple generalized Weyl algebras 4 of Gelfand Kirillov dimension 4, a class including the second Weyl algebra A 2 , some simple factor algebras of the universal enveloping algebra of the Lie algebra sl(2)\_sl(2) and of U q sl(2)\_U q sl(2), etc., the simple holonomic 4-modules are classified up
