cuequivariance.segmented_tensor_product.Subscripts

class cuequivariance.segmented_tensor_product.Subscripts(subscripts: str | list[str])

Represent the subscripts of a Segmented Tensor Product.

Examples

• “ui,uv,vi” could be the subscripts of an equivariant linear layer with shared weights.

• “ui,vj,uvk+ijk” could be the subscripts of a full tensor product (without weights but with Clebsch-Gordan coefficients).
