Description: Definition substitution for a centralizer. (Contributed by Stefan O'Rear, 5-Sep-2015.)
Hypotheses
Ref Expression
cntzfval.b  |-  B  =  ( Base `  M
)
cntzfval.p  |-  .+  =  ( +g  `  M )
cntzfval.z  |-  Z  =  (Cntz `  M )

cntzval  |-  ( S 
C_  B  ->  ( Z `  S )  =  { x  e.  B  |  A. y  e.  S  ( x  .+  y )  =  ( y  .+  x ) } )
Distinct variable groups:    x, y,  .+    x, B    x, M, y   
x, S, y
Allowed substitution hints:    B( y)    Z( x,  y)

Proof of Theorem cntzval
Dummy variables  m  s  w  j are mutually distinct and distinct from all other variables.
