... Theorem 2.2.3. Let A ∈ Mm,n (F ). Then the RREF is necessarily unique. We defer the proof of this result. Let A ∈ Mm,n (F ). Recall that the row space of A is the subspace of Rn (or Cn ) spanned by the rows of A. In symbols the row space is S(r1 (A), . . . , rm (A)). Proposition 2.2.1. For A ∈ Mm,n ...

... Proof. Let dim V = r and let v1 , v2 , . . . , vr be a basis in V . Then the system of vectors Av1 , Av2 , . . . , Avr isa generating system for AV . Indeed, every vector v ∈ V can be αk vk , so any vector of form Av, v ∈ V can be represented as a represented as v = rk=1 linear combination Av = k ...

... Thus Φp (X + 1) satisfies Eisenstein’s Criterion at p by properties of the binomial coefficients, making it irreducible over Z. Consequently, Φp (X) is irreducible: any factorization Φp (X) = g(X)h(X) would immediately yield a corresponding factorization Φp (X + 1) = g(X + 1)h(X + 1) since the mappi ...

... performed in O(n log n) real operations by using the FST, see [16]. Hence the number of operations required for the FST is less than that of the FFT. It was shown in [1] and [12] that a matrix belongs to Bn×n defined by (1) if and only if the matrix can be expressed as a special sum of a Toeplitz ma ...
