Orbifold theory of the affine vertex operator superalgebra $L_{\widehat{osp(1\mathrm{\mid }2)}}(k,0)$

This paper is about the orbifold theory of affine vertex operator superalgebras. Among the main results, we classify the irreducible modules and determine the fusion rules for the orbifold of the simple affine vertex operator superalgebra $L_{\widehat{osp(1\mathrm{\mid }2)}}(k,0)$.
