The solid torus is a connected, compact, orientable 3-dimensional manifold with boundary. The boundary is homeomorphic to S^1 \times S^1, the ordinary torus.
lexicalization	eng: solid torus
instance of	(noun) (mathematics) any set of points that satisfy a set of postulates of some kind; "assume that the topological space is finite dimensional" mathematical space, topological space
