Dear Sage devs, SageManifolds <http://sagemanifolds.obspm.fr/> has been split in various tickets for submission to Sage. They are now ready for review at http://trac.sagemath.org/ticket/18528
This split has been the opportunity to reorganize many things in the project, among which: - the disentanglement of the topology part from the differential one, via the creation of the new class TopManifold <http://sagemanifolds.obspm.fr/doc/19209/reference/manifolds/sage/manifolds/manifold.html>, from which DiffManifold <http://sagemanifolds.obspm.fr/doc/19209/reference/manifolds/sage/manifolds/differentiable/manifold.html> inherits - the possibility to have base fields different from the real numbers, opening the path to complex manifolds - the gathering of all symbolic calculus under a specific class (CoordFunctionSymb <http://sagemanifolds.obspm.fr/doc/19209/reference/manifolds/sage/manifolds/coord_func_symb.html>), the interface with the tensor calculus being performed only via the abstract superclass CoordFunction <http://sagemanifolds.obspm.fr/doc/19209/reference/manifolds/sage/manifolds/coord_func.html>; this should allow to implement "numerical" manifolds (for instance spacetimes resulting from numerical relativity codes, the idea being to use Sage to explore these spacetimes) All the objects are implemented within Sage's category framework, following the parent/element scheme. The category for manifolds is Sets() for the moment, but this should be changed to Manifolds() as soon as #18175 <http://trac.sagemath.org/ticket/18175> is ready. The latest commit, in #19209 <http://trac.sagemath.org/ticket/19209>, should be the basis of the next release of SageManifolds (v0.9) within a few days. Comment/suggestions (and of course reviews!) are most welcome.
