Originally Posted by lehder Hi, F is the group of numerical functions. First "F" you write . Apparently you mean the group of all real functions. Now you write "E" without curly parentheses , but you apparently meant I must show that (H,+) is a subgroup, how to do it please?? 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. Tonio
