Properties of Suslin Sets
- Every Borel set is a Suslin set.
- The collection of all Suslin sets is closed under countable unions and countable intersection.
- Not all Suslin sets are Borel sets (in non-trivial metric spaces such as ).
- If A is a subset of a Polish space then A is a Suslin set if and only if it is an analytic set.
- In a Polish space, any Suslin set is universally measurable.

Famous quotes containing the words properties of, properties and/or sets:
“The reason why men enter into society, is the preservation of their property; and the end why they choose and authorize a legislative, is, that there may be laws made, and rules set, as guards and fences to the properties of all the members of the society: to limit the power, and moderate the dominion, of every part and member of the society.”
—John Locke (1632–1704)
“A drop of water has the properties of the sea, but cannot exhibit a storm. There is beauty of a concert, as well as of a flute; strength of a host, as well as of a hero.”
—Ralph Waldo Emerson (1803–1882)
“Analysis as an instrument of enlightenment and civilization is good, in so far as it shatters absurd convictions, acts as a solvent upon natural prejudices, and undermines authority; good, in other words, in that it sets free, refines, humanizes, makes slaves ripe for freedom. But it is bad, very bad, in so far as it stands in the way of action, cannot shape the vital forces, maims life at its roots. Analysis can be a very unappetizing affair, as much so as death.”
—Thomas Mann (1875–1955)
