Shape of a string/chain/cable/rope?
The height of a string in a gravitational field in 2-dimensions is bounded by $h(x_0)=h(x_l)=0$ (nails in the wall) and also $\int_0^l ds= l$. ($h(0)=h(l)=0$, if you take $h$ as a function of arc ...

Polyakov action as broken symmetry effective action
I would like to ask if it is possible to regard the Polyakov action as an effective action that describes the broken symmetric phase of a more general model.
Could someone draw an analogy with O(N) ...
