Theorem isdilN 35441

Description: The predicate "is a dilation". (Contributed by NM, 4-Feb-2012.) (New usage is discouraged.)

Hypotheses

Ref	Expression
dilset.a	|- A = ( Atoms ` K )
dilset.s	|- S = ( PSubSp ` K )
dilset.w	|- W = ( WAtoms ` K )
dilset.m	|- M = ( PAut ` K )
dilset.l	|- L = ( Dil ` K )

Assertion

Ref	Expression
isdilN	|- ( ( K e. B /\ D e. A ) -> ( F e. ( L ` D ) <-> ( F e. M /\ A. x e. S ( x C_ ( W ` D ) -> ( F ` x ) = x ) ) ) )

Distinct variable groups:   x, K   x, S   x, D   x, F

Allowed substitution hints:   A( x)   B( x)   L( x)   M( x)   W( x)

Proof of Theorem isdilN

Dummy variable f is distinct from all other variables.
