The Weierstrass theorem is refering to the (Weierstrass) [[Extreme value theorem]] which states that a continuous function onfrom a compact (non-empty) space to the real numbers attains a maximum and a minimum (see [http://cepa.newschool.edu/het/essays/math/contin.htm#weierstrass]). The [[Heine-Borel theorem]] is used in the proof of that theorem. [[User:Smmurphy|Smmurphy]]^{([[User talk:Smmurphy|Talk]])} 14:03, 23 August 2006 (UTC)
