flipper.kernel.moves.EdgeFlip

class flipper.kernel.moves.EdgeFlip(source_triangulation, target_triangulation, edge_label)

Bases: flipper.kernel.moves.Move

Represents the change to a lamination caused by flipping an edge.

applied_geometric(lamination, action)

Return the action and condition matrices describing the PL map applied to the geometric coordinates of the given lamination after post-multiplying by the action matrix.

apply_algebraic(vector)

Return the list of algebraic intersection numbers corresponding to the image of the given lamination under self.

apply_geometric(vector)

Return the list of geometric intersection numbers corresponding to the image of the given lamination under self.

encode()

Return the Encoding induced by this isometry.

extend_bundle(triangulation3, tetra_count, upper_triangulation, lower_triangulation, upper_map, lower_map)

Modify triangulation3 to extend the embedding of upper_triangulation via upper_map under this move.

inverse()

Return the inverse of this map.

package()

Return a small amount of data such that self.source_triangulation.encode([data]) == self.encode().

pl_action(index, action)

Return the action and condition matrices describing the PL map applied to the geometric coordinates by the cell of the specified index after post-multiplying by the action matrix.
