摘要

Let M(1) be the vertex operator algebra with the Virasoro element omega associated to the Heisenberg algebra of rank 1 and let M(1)(+) be the subalgebra of M(1) consisting of the fixed points of an automorphism of M(1) of order 2. We classify the simple weak M(1)(+)-modules with a non-zero element w such that for some integer s >= 2, omega(i)w is an element of C-w (i = left perpendiculars/2right perpendicular + 1, left perpendiculars/2right perpendicular + 2,..., s - 1), omega(s)w is an element of C(x)w, and omega(i)w = 0 for all i > s. The result says that any such simple weak M(1)(+)-module is isomorphic to some simple weak M(1)-module or to some theta-twisted simple weak M(1)-module.
