Description: The predicate "is a hermitian operator." (Contributed by NM, 26-Jan-2008.) (New usage is discouraged.)
Hypotheses
Ref Expression
hmoval.8  |-  H  =  ( HmOp `  U
)
hmoval.9  |-  A  =  ( U adj U
)
Assertion
Ref Expression
ishmo  |-  ( U  e.  NrmCVec  ->  ( T  e.  H  <->  ( T  e. 
dom  A  /\  ( A `  T )  =  T ) ) )

Proof of Theorem ishmo
Dummy variable  t is distinct from all other variables.
