Infinite-randomness quantum Ising critical fixed points
In two dimensional space, Rosenbrock function has a long ravine with very steep walls and flat bottom; “because of the curved flat valley the optimization is zig-zagging slowly with small stepsizes towards the minimum” (en.wikipedia.org/wiki/Gradient descent).
Canonical Duality Theory for Solving Minimization Problem of Rosenbrock Function
Narayana number (sequence A1263), which counts Dyck paths of length 2n with k + 1 peaks and k ravines. A peak is an upstep immediately followed by a downstep, and a ravine is a downstep immediately followed by an upstep.
Bijections from weighted Dyck paths to Schroeder paths
Between two consecutive peaks, there must be exactly one ravine, so having k + 1 peaks is equivalent to having k ravines.
Bijections from weighted Dyck paths to Schroeder paths
Any ravine can clearly be “filled in” and replaced with a horizontal step, so a Dyck path with k ravines corresponds to 2k little Schr¨oder paths, which explains equation (1).
