comment Integral for piecewise function inconsistent with the usual way
that shows that your system is really stable. @Michael E2 also reported correct results with Mac machine. My machine is neither Mac nor 64 bit. I have a 32 bit vista ultimate. At least with charger I am able to get correct results. Thanks for the feedback.

comment Integral for piecewise function inconsistent with the usual way
It is now even more interesting. I have a laptop and when I use it at enerysave mode, I got again the wrong answer and when I turned it back to the highperformance mode I got the correct answer.

comment Ploting a topology that accepts saddle point in 3 dimensional plot
Very good work. Thanks alot. One question: why do I have bluelike colors in my plot while your plot has golden colors? I have mathematica 9 on an xp 32 bit machine, if necessary.

comment Ploting a topology that accepts saddle point in 3 dimensional plot
Your guess is completely correct. It means the question was not that bad. However, I still need to know what is the scaled function. Assume you will present this to some people. They will ask what is x axis what is y axis and what is z axis. What must one say?

you so direct person. But you are right, this is the nice point. Thanks alot! I learned it at least for the next time!

I did the labeling already for $x,y,z$ axes and also I changes a few more things. What remains is only those after the red arrows just after the heads of arrows.

comment 3D plot of two spheres with constraint
Thank you very much for your help. It is very beautiful now. Only one more remaning point and the mission is completed. Just after the two arrow heads I would like to put $\epsilon_0$ and $\epsilon_1$, respectively. This is actually written in the question. On the other hand, I always accept the answers, pls have a look at my profile history. Thanks once again.

comment 3D plot of two spheres with constraint
Okay I checked it. except for myplane everything is fine. myplane has the term 1-x-y and this becomes negative for some $x$ and $y$. with the constraint, but for $x+y+z=1$, we also need to have $x>0$, $y>0$ and $z>0$. Mysphere is nice as I wanted. I worked out with your answer and I am updating the question now with only a few missing points.

comment 3D plot of two spheres with constraint
I am sorry. My code is only for one sphere but what I need is two. Since at one I was away from what I needed to have, I didnt try more.
