v0.1.3

Minor updates and bugfixes since March 2024.

• Add function to compute Maskit polynomials and slice, as well as an interactive Maskit slice explorer.
• GroupCache now supports rudimentary generator names.
• Isometric circle generators have built in bounding parameters
• Bugfix: when Y(inf) = inf, then cayley.mobius_fixed_points(Y) was wrong up to sign.
• Pleating ray extensions can be computed right down to the link group (farey.approximate_pleating_ray(end_at_cusp=False))
• Breadth-first limit set algorithm
• Updates to examples

v0.1.2

• Major bugfixes to circle space action
• Remove a couple of minor examples that are no longer helpful

Full Changelog: v0.1.1...v0.1.2

v0.1.1

v0.1.1

• The primary improvements in this version are related to Farey sequences and Farey word:
  • Added continued fractions algorithms to farey module
  • Better peripheral splittings function, farey.standard_peripheral_generators()
  • Add algorithms to compute rational pleating rays, see examples/parabolic_slice_pleating_rays.py
• Other miscellaneous changes:
  • Add accidental parabolic example and an example of (1;2)-compression body groups.
  • Compute Lyndon-Ullman bounds in the Riley slice explorer

Full Changelog: v0.1.0...v0.1.1

v0.1.0

v0.1.0

• Bug #21: only compute coprime primitice slices and raise exception with helpful error on failed convergence
• Add interactive tool for exploring Riley slices
• Bugfix: slices.elliptic_exterior() failed if p or q were infinite
• Add Schottky groups to examples
• Add miscellaneous utility functions to Cayley that work directly with Mobius transformations:
  • action_on_circles(), which computes the action of Mobius transformations on the projective space of circles
  • three functions to convert usual parameters for circles and lines into the corresponding points of the projective space of circles
  • normalise_mobius_pair(), which normalises a pair of Mobius transformations to fix 0, infinity, and map 0->1.

Full Changelog: v0.0.99...v0.1.0

v0.0.99

• a myriad of new examples
• new method in cayley to construct groups by taking orientation-preserving half of group generated by circle inversions
• faster limit set calculation via random walks with one point
• automatically determine peripheral subgroups of Riley groups
• improved test coverage

Full Changelog: v0.0.98.post1...v0.0.99

v0.0.98.post1

v0.0.98.post1

• delete ununused code in riley.py that depends on deprecated package not in dependencies
  v0.0.98
• FIX incorrect computation of Farey polynomials
• Increase mpmath precision
• Add some unit tests
• Change Farey polynomials to work with initial traces instead of matrix entries
• Allow computation of Farey words and polynomials after substituting for the generators
• New syntax for generating Riley slice approximations (slice.py) which allows for
  experiments involving different Farey word substitutions.
• Improve examples

v0.0.97

v0.0.97

• Computation of Riley slice approximations (moduli.py).
• Convert all internals to use mpmath instead of numpy.
• Add methods (farey.riley_string(), farey.riley_polynomial_*()) to compute Riley words and polynomials.
• examples/plotslice.py now is interactive and shows both Riley and Farey polynomial approximations.
• Add method (cayley.GroupCache.coloured_isometric_circles_mc()) to produce isometric circles.
• Rename some methods in farey to make them less ambiguous.
• Remove functions in farey that compute Phi^inf,inf - 2 because there is no point in having them.

v0.0.96

v0.0.96

• Construction of Riley groups now takes a holonomy angle not an order (use riley.ClassicalRileyGroup for old behaviour).
• Add new feature to `guess' which pleating ray a particular Riley group lies on (riley.RileyGroup.guess_rational_coordinate()).

v0.0.95

Minimum viable product without Riley slice computations.
