Query: A certain class of standard subalgebras of affine Kac-Moody algebras   The aim of this paper is to extend the theory of standard subalgebras of
finite dimensional simple Lie algebras to infinite dimensional Lie algebras. We
construct and characterize a class of standard subalgebras of affine Kac-Moody
algebra.
