Theorem erngset 36088

Description: The division ring on trace-preserving endomorphisms for a fiducial co-atom W. (Contributed by NM, 5-Jun-2013.)

Hypotheses

Ref	Expression
erngset.h	|- H = ( LHyp ` K )
erngset.t	|- T = ( ( LTrn ` K ) ` W )
erngset.e	|- E = ( ( TEndo ` K ) ` W )
erngset.d	|- D = ( ( EDRing ` K ) ` W )

Assertion

Ref	Expression
erngset	|- ( ( K e. V /\ W e. H ) -> D = { <. ( Base ` ndx ) , E >. , <. ( +g ` ndx ) , ( s e. E , t e. E |-> ( f e. T |-> ( ( s ` f ) o. ( t ` f ) ) ) ) >. , <. ( .r ` ndx ) , ( s e. E , t e. E |-> ( s o. t ) ) >. } )

Distinct variable groups:   f, s, t, K   f, W, s, t

Allowed substitution hints:   D( t, f, s)   T( t, f, s)   E( t, f, s)   H( t, f, s)   V( t, f, s)

Proof of Theorem erngset

Dummy variable w is distinct from all other variables.
