Basic Examples
(3)
A pairwise binary chain has only two-tensor indices, so the predicate is True:
In[1]:=
BinaryTensorNetworkQ[TensorNetwork[{{1,2},{2,3},{3,4}}]]
Out[1]=
True
When a single index is shared by three tensors, the network has a hyperedge and the predicate is False:
In[1]:=
BinaryTensorNetworkQ[TensorNetwork[{{1,2},{1,3},{1,4}}]]
Out[1]=
False
BinaryTensorNetwork inserts a spider tensor for every hyperedge, after which the predicate returns True:
In[1]:=
hyper=TensorNetwork[{{1,2},{1,3},{1,4}}];hyper["BinaryQ"]
In[2]:=
BinaryTensorNetworkQ[BinaryTensorNetwork[hyper]]
Out[2]=
False
Out[2]=
True
