A classification of lowest weight irreducible modules over ${\mathbb{Z}}_2^2$-graded extension of $osp(1|2)$

K. Amakawa, N. Aizawa

We investigate representations of the ${\mathbb{Z}}_2^2$-graded extension of $osp(1|2)$ which is the spectrum generating algebra of the recently introduced ${\mathbb{Z}}_2^2$-graded ve…
