Inner form
text:
In mathematics, an inner form of an algebraic group G over a field K is another algebraic group H such that there exists an isomorphism ϕ between G and H defined over K ¯ and in addition, for every Galois automorphism σ ∈ G a l the automorphism ϕ − 1 ∘ ϕ σ is an inner automorphism of G . Through the correspondence between K -forms and the Galois cohomology H 1 this means that H is associated to an element of the subset H 1 where I n n is the subgroup of inner automorphisms of G .
