Emergence in graphs with near-extreme constraints

Charles Radin, Lorenzo Sadun

We consider entropy-optimal graphons associated with extreme and near-extreme constraints on the densities of edges and triangles. We prove that the optimizers for near-extreme con…

How big is a tiling's return module?

Abigail Perryman, Lorenzo Sadun

The rank of a tiling's return module depends on the geometry of its tiles and is not a topological invariant. However, the rank of the first \v Cech cohomology give…

Dynamics and topology of the Hat family of tilings

Michael Baake, Franz Gähler, Lorenzo Sadun

The recently discovered Hat tiling admits a 4-dimensional family of shape deformations, including the 1-parameter family already known to yield alternate monotiles. The continuous…

Optimal graphons in the edge-2star model

Charles Radin, Lorenzo Sadun

In the edge-2star model with hard constraints we prove the existence of an open set of constraint parameters, bisected by a line segment on which there are nonunique entropy-optima…

Existence of a symmetric bipodal phase in the edge-triangle model

Joe Neeman, Charles Radin, Lorenzo Sadun

In the edge-triangle model with edge density close to 1/2 and triangle density below 1/8 we prove that the unique entropy-maximizing graphon is symmetric bipodal. We also prove tha…

Typical large graphs with given edge and triangle densities

Joe Neeman, Charles Radin, Lorenzo Sadun

The analysis of large simple graphs with extreme values of the densities of edges and triangles has been extended to the statistical structure of typical graphs of fixed intermedia…
