We generalizes the theta functions on vertex operator algebras and prove that the internal automorphisms do not change the genus one twisted conformal blocks.Latex2e 24 pages, a reference is revised v4: we add a section on abelian coset constructionQuantum Algebra17B69; 11F11Modularity on vertex operator algebras arising from semisimple primary vectorstext
