What ⊠ means
The author defines the operation in the surrounding notation. In vertex-operator-algebra theory, ⊠ denotes a fusion product between modules, mathematical structures an algebra acts on. Its exact rule comes from that theory.
Formal mathematical notation; the author defines the operation.
Check the author's definition before treating it as ordinary multiplication.
