Thanks to all for your replies,

Your're right "y" was meant to be an unknown constant. As I understand 
it know, Maximize[] does some sort of numerical optimization. I thought 
it would be able to use some concave Programming logic (like 
Kuhn-Tucker) to solve this problem for me, returning a list of possible 
optima in symbolic form together with the neccessary constraints... But 
I admit that maybe this is to much to ask for ;-)

Greetings,
