Liouville Number
A Liouville number is a Transcendental Number which has very close Rational Number approximations. An IrrationalNumber 
is a Liouville number if, for any 
, there exist an infinite number of pairs of Integers 
and 
such that
Mahler (1953) proved that
is not a Liouville number.See also Liouville's Constant, Liouville's Rational Approximation Theorem, Roth's Theorem, TranscendentalNumber
