flipper.kernel.moves.LinearTransformation

class flipper.kernel.moves.LinearTransformation(source_triangulation, target_triangulation, geometric, algebraic)

Bases: flipper.kernel.moves.Move

Represents the change to a lamination caused by a linear map.

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.

inverse()

Return the inverse of this map.

Note that these do not exist and so NotImplemented is returned.

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.
