Surely they exist, surely they can be simultaneously measured, it's just that by performing simultaneous measurements on an infinity of...

I think we can prove that ##M## is positive definite because it corresponds to the following quadratic form...

So my current status is the following. I am evaluating the Hessian ##H## of ##V## to look at the eigenvalues for the equilibrium...

Thanks a ton for your help. Do I have to mark this as solved, or close it, or something? thanks

Yes. I think it indeed has to do with the interplay with the constraint forces Things get complicated long before...

Thank you! I think you plotted my formula for ##V## when varying just one of the ##\alpha_i## right? Thinking about this, I think that...

Here is the complete statement (I will omit the book it comes from as I dont't know the policy of this forum): Consider ##l## equal...

thanks BvU for your reply. Actually the way in which I wrote the formula was a bit ambigous, I will re-edit the post with...

Welcome to PF. :smile: It's good to have you here.

I use ##l-1## lagrangian coordinates ##\alpha_1,...,\alpha_{l-1}## . ##\alpha_i## is the angle between ##OP_{i-1}## and ##OP_{i}##. As...

Hi everyone, IT professional from Italy, I have always been fascinated by maths and fundamental physics. Here to learn more about...
