Your love is an allurement and a dare
Set for attainment, like a shining spire,
Far, far above me in the starry air:
And gazing upward, 'gainst the hope of hope,
I breast the slope, I breast the slope.

In science:

We also prove that the surface tension is strictly convex and that if u is in the interior of the space of finite-surface-tension slopes, then there exists a minimal energy gradient phase µu of slope u.
Random Surfaces
Whenever µ has slope u which lies on the boundary of UΦ , we say that µ is taut and that u is a taut slope.
Random Surfaces
Clearly, such a measure has finite slope, so (by definition of σΦw ) it must have slope u and specific free energy equal to σ(u).
Random Surfaces
Since the variational principle and the uniqueness of the gradient phase of slope u (as shown in Chapter 8) may not apply when u is one of these boundary slopes, we cannot expect the minimizer of the rate function to be unique in this case.
Random Surfaces
Here, we give an example of an LSAP Φ and a slope u ∈ UΦ for which the gradient phase of slope u is not unique (and a sketch of the proof that it is not unique).
