WebW a subspace of V. Then, W is also nite dimensional and indeed, dim(W) dim(V). Furthermore, if dim(W) = dim(V), then W=V. Proof. Let Ibe a maximal independent set in W Such a set exists and is nite because of the fundamental inequality. Ispans W, and so is a basis for W. This is due to the dependence lemma showing that spanI= W. WebFeuilled’exercicesno 20:dimensionfinie Exercice 1. Déterminerladimensiondesensemblessuivants: …

In F^6, give an example of two independent and disjoint sequences of vectors (v1,v2,v3) and (w1,w2,w3) such that: a. Span(v1,v2,v3) = Span(w1,w2,w3). b.dim[ Span(v1,v2,v3) ∩ Span(w1,w2,w3)] = 2. WebIn this paper, we study the structural properties of ( α + u 1 β + u 2 γ + u 1 u 2 δ ) -constacyclic codes over R = F q [ u 1 , u 2 ] / u 1 2 − u 1 , u 2 2 − u 2 , u 1 u 2 − u 2 u 1 where q = p m for odd prime p and m ≥ 1 . We derive the generators of constacyclic and dual constacyclic codes.

WebLet V be a vector space over F, and let U and W be subspaces of V. Then U∩W is also a subspace of V. Proof: (i) 0 ∈ U ∩W, since 0 ∈ U and 0 ∈ W. (ii) If u,v ∈ U ∩W, then u+v ∈ U and u+v ∈ W, since each of u and v are, so u+v ∈ U ∩ W. (iii) Similarly if a ∈ F and u ∈ U ∩W, then au ∈ U and au ∈ W so au ∈ U ∩W.
