Theorem islmhm3 19028

Description: Property of a module homomorphism, similar to ismhm 17337. (Contributed by Stefan O'Rear, 7-Mar-2015.)

Hypotheses

Ref	Expression
islmhm.k	|- K = (Scalar ` S )
islmhm.l	|- L = (Scalar ` T )
islmhm.b	|- B = ( Base ` K )
islmhm.e	|- E = ( Base ` S )
islmhm.m	|- .x. = ( .s ` S )
islmhm.n	|- .X. = ( .s ` T )

Assertion

Ref	Expression
islmhm3	|- ( ( S e. LMod /\ T e. LMod ) -> ( F e. ( S LMHom T ) <-> ( F e. ( S GrpHom T ) /\ L = K /\ A. x e. B A. y e. E ( F ` ( x .x. y ) ) = ( x .X. ( F ` y ) ) ) ) )

Distinct variable groups:   x, B   y, E   x, y, S   x, F, y   x, T, y

Allowed substitution hints:   B( y)   .x. ( x, y)   .X. ( x, y)   E( x)   K( x, y)   L( x, y)
