Representations of the Twisted Heisenberg--Virasoro Algebra at Level Zero
Printed: Dec 2003
We describe the structure of the irreducible highest weight modules
for the twisted Heisenberg--Virasoro Lie algebra at level zero. We
prove that either a Verma module is irreducible or its maximal
submodule is cyclic.
