A boundary-bulk conformal field theory is a theory with one-dimensional boundaries realized by a one-dimensional lattice Hamiltonian model, together with its open and closed chiral…

Let $V$ be a rational vertex operator algebra, and let an open-closed field algebra over $V$ consist of the genus-zero open-closed operations. The modular invariance condition is t…

Let $V$ be a rational vertex operator algebra. A self-dual open-closed field algebra over $V$ has non-degenerate symmetric invariant bilinear forms on its open and closed state spa…
