discusses aspects and open problems of understanding

• 3d Chern-Simons theory$\leftarrow$holographic principle$\to$ 2d WZW model

• 7d Chern-Simons theory$\leftarrow$holographic principle$\to$ 6d (2,0)-supersymmetric QFT

in the context of extended TQFT.

One explicit version of

• 3d Chern-Simons theory$\leftarrow$holographic principle$\to$ 2d WZW model

is the relation Turaev-Viro model $\leftrightarrow$ Crane-Yetter model due to theorem 2 in
