... properties: (1) if S ⊂ U and if U is a subspace in V , then S ⊂ U ; (2) the linear span of a subset S ⊂ V is the intersection of all subspaces com- prising this subset S. Proof. Let u ∈ S and S ... minimal spanning system of vectors in V is linearly independent. If a spanning system of vectors S ⊂ V is not minimal, then there is some smaller spanning subsystem S   S, i. e...

... special vector spaces and Smarandache pseudo vector spaces, study them and give some of its basic properties. D EFINITION 2.7.1: Let G be S- semigroup and K any field. We say G is a Smarandache ... subgroups of G, that is the number of proper subsets in G which are subgroups of G. Thus, this gives a method of finding several representations i H ρ on V, V a S- vector space o...

... R-modules in general is important and complex. However the study of F -modules is short and simple – every vector space is free and every subspace is a summand. The core of classical linear algebra ... Mathematics has its own universally accepted shorthand. The symbol ∃ means “there exists” and ∃! means “there exists a unique”. The symbol ∀ means “for each” and ⇒ means “implies”...
