I'm not sure if it is justified to call "composition operator" the operator C_g rather than the operator "o" itself. To be not too invasive, I just added a kind of "otheruse" preamble, but maybe one should go a bit further (I think more people would think of "o" rather than of Cg when they hear "composition operator" in a general context.) — MFH:Talk 18:31, 16 October 2006 (UTC)

yes, this confused me. If I have a function g o f then I guess g and f are operands of the operator "o". I guess just f is an operand of the operation C_g(f)? If so (and this is what I really want to know) what do we call g? Perhaps a parameterized operand of the operator C?220.253.85.77 03:56, 26 April 2007 (UTC)
