Birkhoff-Grothendieck theorem — In mathematics, the Birkhoff Grothendieck theorem concerns properties of vector bundles over complex projective space mathbb{CP}^1 . It reduces every vector bundle over mathbb{CP}^1 into direct sum of tautological line bundles, which enables one… … Wikipedia
Birkhoff's theorem (relativity) — In general relativity, Birkhoff s theorem states that any spherically symmetric solution of the vacuum field equations must be stationary and asymptotically flat. This means that the exterior solution must be given by the Schwarzschild metric.The … Wikipedia
Birkhoff's theorem (electromagnetism) — In physics, in the context of electromagnetism, Birkhoff s theorem concerns spherically symmetric static solutions of Maxwell s field equations of electromagnetism. The theorem is due to George D. Birkhoff. It states that any spherically… … Wikipedia
