On the automorphisms of the classical groups
WebAutomorphism is a permutation of a set which respects some structure on the set. What structure? It varies. Automorphism is a general term and does not apply simply to groups, or rings. In the context of (Z, +) as an additive group, we say that f: Z → Z is an automorphism if: f is a bijection, f(m) + f(n) = f(m + n), f(0) = 0. WebThe group QC(X) of quasiconformal automorphisms ω: X→ Xacts on Def(X) by ω((φ,Y)) = (φ ω−1,Y). The Teichmu¨ller space Teich(X) parameterizes complex structures on Xup to isotopy. More precisely, we will define below a normal subgroup QC 0(X) ⊂ QC(X) consisting of self-maps isotopic to the identity in an appropriate sense; then
