Description (last modified by mkoeppe)

New subsets:

  • #31674 Make open subsets of immersed/embedded submanifolds immersed/embedded submanifolds
  • #31677 Open subsets of arbitrary subsets of manifolds
  • #31653 Images of continuous maps and embedded submanifolds as manifold subsets
  • #31644 Topological closure of manifold subsets, embedded submanifolds
  • #31688 Pullbacks of manifold subsets under continuous maps
  • #31724 ManifoldFiniteSubset
  • #31685 ContinuousMap.image: if map is an isomorphism and domain_subset is open, create a submanifold

Families and posets of manifold subsets:

  • #31680 Poset of manifold subsets
  • #31718 ManifoldSubset: Change some methods to generators
  • #31732 ManifoldSubset: New methods declare_empty, declare_nonempty, is_empty, has_defined_points, open_cover_family
  • #31727 ManifoldSubset: Add methods subset_family, superset_family, open_superset_family; deprecate method list_of_subsets
  • #31736 ManifoldSubset: New methods declare_equal, equal_subsets, equal_subset_family
  • #31738 ManifoldSubset.intersection: Compute more supersets
  • #31682 manifolds: Add _test_... methods that check invariants of subset relations
  • #30263 declare_union yields wrong results

Topological tools:

  • #31741 ManifoldSubset.separating_open_supersets

Application to polyhedra and optimization:

  • #31659 Polyhedron.affine_hull_manifold
  • #31660 Polyhedron.relative_interior_manifold
  • #31728 manifolds.Sphere: Make relation to simplicial spheres more concrete
  • #31742 MixedIntegerLinearProgram.ambient_manifold, feasible_subset, objective_scalar_field, optimal_subset
