Description: A property that determines the adjoint of a Hilbert space operator. (Contributed by NM, 20-Feb-2006.) (New usage is discouraged.)
Assertion
Ref Expression
adjeq  |-  ( ( T : ~H --> ~H  /\  S : ~H --> ~H  /\  A. x  e.  ~H  A. y  e.  ~H  (
( T `  x
)  .ih  y )  =  ( x  .ih  ( S `  y ) ) )  ->  ( adjh `  T )  =  S )
Distinct variable groups:    x, y, S    x, T, y

Proof of Theorem adjeq
Dummy variables  w  z are mutually distinct and distinct from all other variables.
