Theorem issubassa2 15144

Description: A subring of a unital algebra is a subspace and thus a subalgebra iff it contains all scalar multiples of the identity. (Contributed by Mario Carneiro, 9-Mar-2015.)

Hypotheses

Ref	Expression
issubassa2.a	|- A = (algSc ` W )
issubassa2.l	|- L = ( LSubSp ` W )

Assertion

Ref	Expression
issubassa2	|- ( ( W e. AssAlg /\ S e. (SubRing ` W ) ) -> ( S e. L <-> ran A C_ S ) )

Proof of Theorem issubassa2

Dummy variables x y are mutually distinct and distinct from all other variables.
