Several theorems are named after Karl Weierstrass. These include:

  • The Weierstrass approximation theorem, of which one well known generalization is the Stone–Weierstrass theorem
  • The Bolzano–Weierstrass theorem, which ensures compactness of closed and bounded sets in R<sup>n</sup>
  • The Weierstrass extreme value theorem, which states that a continuous function on a closed and bounded set obtains its extreme values
  • The Weierstrass–Casorati theorem describes the behavior of holomorphic functions near essential singularities
  • The Weierstrass preparation theorem describes the behavior of analytic functions near a specified point
  • The Lindemann–Weierstrass theorem concerning the transcendental numbers
  • The Weierstrass factorization theorem asserts that entire functions can be represented by a product involving their zeroes
  • The Sokhatsky–Weierstrass theorem which helps evaluate certain Cauchy-type integrals
