... Problem 5. Let A be a finite set, B ⊂ A be a subset, and let b ∈ B be one particular element of B. Determine whether the given set is a subgroup of SA under induced operation. Here σ[B] = {σ(x) | x ∈ B} 1. {σ ∈ SA | σ[B] = B}. 2. {σ ∈ SA | σ[B] ⊂ B} Solution: We will only deal with the first part, s ...

... Proof Again we have seen that A is congruent to a matrix of this form. Arguing as in the complex case, we see that s + t = rank(A), and so any two matrices of this form congruent to A have the same values of s + t. Moreover, by restricting to a subspace on which A is invertible, we may assume withou ...
