curver.kernel.twist.HalfTwist¶
-
class
curver.kernel.twist.
HalfTwist
(arc, power)[source]¶ Bases:
curver.kernel.moves.FlipGraphMove
This represents the effect of half-twisting a short arc.
This format allows us to efficiently perform powers of twists.
-
apply_homology
(homology_class)[source]¶ Return the homology class obtained by mapping the given homology class through this move.
-
apply_lamination
(lamination)[source]¶ Return the lamination obtained by mapping the given lamination through this move.
-
encode
()¶ Return the Encoding induced by this move.
-
flip_mapping
()[source]¶ Return a Mapping equal to self.encoding() but that only uses EdgeFlips and Isometries.
