A Disconnected extremums of an action

    If you want to find the extremums of an action, you just solve the associated Euler-Lagrange equations. But this procedure gives you only the continuous extremums. There may be extremums that consist of two separate pieces, like two separate surfaces. How would you find out whether such a solution exists for a given action or not?
    Thanks

    Thanks for the thread! This is an automated courtesy bump. Sorry you aren't generating responses at the moment. Do you have any further information, come to any new conclusions or is it possible to reword the post? The more details the better.
