Hi,

First "F" you write . Apparently you mean the group of all real functions.




Now you write "E" without curly parentheses , but you apparently meant

Now you talk about some "H" (?), which I suppose should be "E", but you don't tell us how the sum "+" is defined there...

Please do check the way you wrote the question and be clearer.
