FIG. 1.

A graph edge representing both the Hopf algebra H (via L ±) and X = (H op)* (via T ±). These different H- and X-module structures are related via and , respectively.

Degenerate vertices and faces with spikes and loops.

Decorated face.

FIG. 5.

Proper faces (white) vs. boundary “faces” F M (light red). Upon continuous deformation of those pieces of the boundary ∂M which do not coincide with graph edges (dashed gray) the vertices marked in gray on the left and on the right are identified with each other, respectively. The boundary faces F M are precisely those which are completed to proper faces by this process. Furthermore, both the boundary edges E M (red) and interior edges (black) are shown.

FIG. 6.

A region R whose boundary ∂R never crosses any interior edges cleanly partitions the edges into the set E R (black, red) which belongs to R and the rest (gray). The internal boundary (∂R)° consists of those pieces which do not coincide with the boundary of the ambient surface M and gives rise to the internal boundary faces (light red, middle).

FIG. 7.

Diagram encoding the tensor trace . While the interior degrees of freedom {x e } ⊂ H and {f p } ⊂ X are only shown partially the boundary degrees of freedom {y e } ⊂ H and {g q } ⊂ X are labelled in such a way that the ordering of the boundary is evident.

Hierarchy of Hopf tensor network states for before the partial collapse. Subalgebras and are ordered by dimension, not necessarily by inclusion. Surviving equivalence classes of quantum states share the same value of the topological entanglement entropy γ, see Sec. V for a detailed discussion.

Hopf tensor network state on a small graph Γ embedded in S 2. The outer circle is identified with the north pole of S 2.
