Suslin Set - Properties of Suslin Sets

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)

    Eddie did not die. He is no longer on Channel 4, and our sets are tuned to Channel 4; he’s on Channel 7, but he’s still broadcasting. Physical incarnation is highly overrated; it is one corner of universal possibility.
    Marianne Williamson (b. 1953)
