Dear all, I defined enumerations "Theorem", "Proof", and "Example" as in the sample code. It works fine, but I'd like to arrange it in better shape. 1. Theorem 1 and it's proof look good. 2. The proof of Theorem 2 i) when I use \startitemize it starts from the next line not immediately after "Proof". Q: How to start the sentence right after "Proof"? ii) after \stopitemize, it changes the line and put blacksquare at the end. So, there is a blank line always. Q: How to place blacksquare at the end of the last line of the sentence? iii) leading symbol of itemize, "b" is inside the figure. Q: How to correct this or is it possible to place the figure at the right side? 3. I'd like to put "Example" and it's number in a frame, but I couldn't. Is there a way of doing that? Should I make a new command to do that? Thank you for reading. Best regards, Dalyoung
