Bear
Bear is a tool for calculating and testing discreteness of holonomy representations of complex projective structures on punctured tori. It can be used to draw pictures of Bers slices and explore the geometry of quasifuchsian space in the SL_2(C) representation variety. It also has powerful scripting features that make it easy to create complex animations or to automate larger calculations.

- 31 Dec 2007 09:55
Changes: This release includes bugfixes, code improvements, and a new module for computing McShane-type sums over the tree of Markov triples.
- 14 Aug 2005 01:31
Changes: This is a bugfix release that also includes performance improvements resulting from the same issues addressed in the 0.9.5 bugfixes. This is also the first release of Bear which is available in RPM package format. Packages for several popular i386 GNU/Linux distribtuions and a source RPM are included. Binary DEB packages for Debian GNU/Linux on i386 and AMD64 and for Ubuntu GNU/Linux on i386 are also available.

Changes: This is a bugfix release that also incorporates minor feature enhancements. The build system is now more robust and portable, and problems building on Darwin / Mac OS X have been fixed. A new ODE solver 'LSODE' was added, and a new 'blocking' feature eases the subdivision of larger calculations into small pieces for distributed computing.

Changes: New features include support for several types of Schwarzian equation integration contours (splines, ellipses, and piecewise linear paths), and a new module 'bers2' for computing holonomy on a sparse grid and then interpolating over a finer grid. An experimental module 'anosov' for computing unstable manifolds of pseudo-anosov mapping classes was added. Several minor usability improvements were made.
