Theorem dvafplusg

Description: Ring addition operation for the constructed partial vector space A. (Contributed by NM, 9-Oct-2013) (Revised by Mario Carneiro, 22-Jun-2014)

Ref Expression
Hypotheses dvafplus.h H = LHyp K
dvafplus.t T = LTrn K W
dvafplus.e E = TEndo K W
dvafplus.u U = DVecA K W
dvafplus.f F = Scalar U
dvafplus.p + ˙ = + F
Assertion dvafplusg K V W H + ˙ = s E , t E f T s f t f
