First excuse my question which is probably easy to answer for the high-level Mathematica users that you are. I have to simultaneously solve equations corresponding to a physical problem. Therefore most of my variables have a meaning only if they are real and positive. How can I say to Mathematica that it has to reject solutions not corresponding to these cases, and furthermore how to declare these variables so that their particular nature is used by Simplify or FullSimplify. Thanks in advance
