In abstract algebra, a field is a ring whose nonzero elements form a commutative group under multiplication.
From the en.wikipedia.org
More generally, every commutative topological group is also a uniform space.

However, matrix multiplication is not commutative, therefore this group is nonabelian.
From the en.wikipedia.org
A non-commutative topological group, however, carries two uniform structures, one left-invariant, the other right-invariant.

The problem is to determine if a black box group, given by k generators, is commutative.
From the en.wikipedia.org
If the symmetry group is non-commutative, the gauge theory is referred to as non-abelian, the usual example being the Yang-Mills theory.
From the en.wikipedia.org
Current theories relating to the symmetric group and symmetric functions, commutative algebra, moduli spaces and the representations of Lie groups are rooted in this area.
From the en.wikipedia.org
In group and set theory, many algebraic structures are called commutative when certain operands satisfy the commutative property.
