Theorem vri 14834

Description: The properties of a real vector space, which is an abelian group (i.e. the vectors, with the operation of vector addition) accompanied by a scalar multiplication operation on the field of real numbers. The variable W was chosen because _V is already used for the universal class.

Hypotheses

Ref	Expression
vri.1	|- G = (1st` W)
vri.2	|- S = (2nd` W)
vri.3	|- X = ran G

Assertion

vri	|- (W e. RVec -> (G e. Abel /\ S:(RR X. X)-->X /\ A.x e. X ((1Sx) = x /\ A.y e. RR (A.z e. X (yS(xGz)) = ((ySx)G(ySz)) /\ A.z e. RR (((y + z)Sx) = ((ySx)G(zSx)) /\ ((y x. z)Sx) = (yS(zSx)))))))

Distinct variable groups:   x,G,y,z   x,S,y,z   x,X,z
