2d Conformal Field Theories on Magic Triangle

Kimyeong Lee, Kaiwen Sun

The magic triangle due to Cvitanović and Deligne--Gross is an extension of the Freudenthal--Tits magic square of semisimple Lie algebras. In this paper, we identify all two-dimensi…

On intermediate Lie algebra $E_{7 + 1/2}$

Kimyeong Lee, Kaiwen Sun, Haowu Wang

$E_{7 + 1/2}$ is an intermediate Lie algebra filling a hole between $E_{7}$ and $E_{8}$ in the Deligne-Cvitanović exceptional series. It was found independently by Mathur, Muhki, Sen in…
