Commuting indeterminates
WebFormal power series in N non-commuting indeterminates can be considered as a counterpart of functions of one variable holomorphic at 0, and some of their properties are described in terms of coefficients. However, really fruitful analysis begins when one considers for them evaluations on N-tuples of n × n matrices (with n = 1, 2, ⋯) or … WebApr 1, 2013 · Recall that A n , the group of even permutations of {1,...,n}, contains the cycles of odd length. Theorem 3. Let n 3 and A, B ∈ M n (K) be such that they have a common invariant proper vector subspace over an extension field of K. We assume that χ A is irreducible over K and G A = S n or G A = A n . Then AB = BA.
