Abstract
We study the structure of imaginary Verma modules induced from the "natural " Borel subalgebra of a toroidal Lie algebra. In particular, we establish a criterion of irreducibility for imaginary Verma modules and describe their submodules and irreducible quotients. We also describe the structure of Ve rma type modules in the case of sl(2)-toroidal Lie algebra over two variabl es.
