Chromatic characters and root multiplicities for Borcherds--Kac--Moody algebras

Priyanshu Chakraborty, Supriya Saha, R. Venkatesh

The main aim of this article is to obtain explicit formulas for the root multiplicities of a class of finite-rank symmetrizable Borcherds-Kac-Moody algebras g(A) whose real part is…
