<p>The notion of Verma-type modules for affine Lie algebras is related to the concept of Borel subalgebras. The literature is extensive when the affine algebra is untwisted and all constructions come from Borel subalgebras of the adjacent finite-dimensional simple Lie algebra. However, I did not find any reference in the case of twisted affine algebras. </p> <p>What is a reference for Borel (parabolic) subalgebras of twisted affine algebras?</p>
