## borderbasis.LiftAS

Compute eqns defining BB scheme and coming from lifting of AS neighbors

### Syntax

$borderbasis.LiftAS(OO:LIST):LIST

### Description

Compute the equations defining the border basis scheme and coming from the lifting of across-the-street neighbors. The input is a list of terms OO (2nd element of type POLY). The output is a list of poly in the ring <formula>BBS=K[c_{ij}]</formula>.
