A basis theorem for Genus-One Conformal Blocks and modular invariance of intertwining operators
Xu Gao, Jianqi Liu
We prove that trace functions associated to intertwining operators over a strongly rational vertex operator algebra form a global frame of the conformal block bundle $\mathscr{C}_{…

On strong identities of almost-canonically seminormed rings
Xu Gao, Jianqi Liu
We investigate the strong identity condition (SIC) for almost-canonically seminormed rings, a class of topological graded rings that includes enveloping algebras of vertex operator…
