- A complete linear vector space
Hilbert space
- A complete inner product space (also a Banach space)
- Well defined concept of orthogonality or angle
- Norm induced by the associated inner product
Closed set
- contains all its limit points
- complement of an open set
Complete set (M)
- every Cauchy sequence of points in M has a limit in M
- there are no points missing (inside or at the boundary)
