automorphism
autoˈmorphism 1. The ascription of one's own characteristics to another.1873 H. Spencer Stud. Sociol. vi. 117 Our interpretations must be automorphic; and yet automorphism perpetually misleads us. 2. Math. (See quots.)1903 Science 5 June 904 Class of a group and degree of transitivity, automorphism,... Oxford English Dictionary

Automorphism group of a free group
In mathematical group theory, the automorphism group of a free group is a discrete group of automorphisms of a free group. Nielsen, and later Bernhard Neumann used these ideas to give finite presentations of the automorphism groups of free groups. wikipedia.org

What is an outer automorphism? I know that an automorphism of a group is just an isomorphism of that group with itself. I know that an _inner_ automorphism is an isomorphism/automorphism of the form $\phi_g$ where $\p...
An **outer automorphism** is just an automorphism that is not an inner automorphism. So confusingly, the elements of the outer automorphism group are _not_ outer automorhims, but rather equivalence classes of outer automorphisms ...

Automorphism group
Examples If X is a set with no additional structure, then any bijection from X to itself is an automorphism, and hence the automorphism group of X in The unit group of is the automorphism group . wikipedia.org

There is an automorphism of $\mathbb Z_6$ which is not an inner automorphism I'm trying to show that there is an automorphism of $\mathbb Z_6$ which is not an inner automorphism. Since the generators of $\mathbb Z_6$ ...
So you only need to find a nontrivial automorphism. Again, since this group is abelian, the inversion map is an automorphism (which is nontrivial in this case).

IA automorphism
An IA automorphism is thus an automorphism that sends each coset of the commutator subgroup to itself. The IA automorphisms of a group form a normal subgroup of the automorphism group. Every inner automorphism is an IA automorphism. wikipedia.org

Let $\alpha=2^{1/5}$ ,$\zeta=e^{2i\pi/5}$ and $K=\mathbb{Q}(\alpha\zeta)$, can the field automorphism of K be extended to an automorphism of C? Let $\alpha=2^{1/5} $ and $\zeta=e^{2i\pi/5}$.Let $K=\mathbb{Q}(\alpha\ze...
Take one of those, not the identity, and extend it to an automorphism of $\bf C$, and you're done.

多重重要性采样 - Automorphism - GitHub Pages
多重重要性采样（multiple importance sampling，MIS）的思路是结合多种不同的采样方法，分别采样被积函数的不同部分，并将这些采样点结合起来，以达到接近于最优采样的结果。 多采样模型（The multi-sample model） 给定待求值的积分： \[\int_\Omega f(x)d\mu(x)\]

Kolmogorov automorphism
