Improving energy absorption capability of the hexagonal honeycomb and re-entrant structures using a combined hierarchical design [PDF]
Scientific ReportsHexagonal honeycombs and re-entrant lattices have been widely used in energy-absorption applications. The hexagonal honeycomb structure, known for its positive Poisson’s ratio and high specific stiffness and strength, has long been considered an ...

On well-rounded sublattices of the hexagonal lattice
Discrete Mathematics, 2010 We produce an explicit parameterization of well-rounded sublattices of the hexagonal lattice in the plane, splitting them into similarity classes. We use this parameterization to study the number, the greatest minimal norm, and the highest signal-to-noise ratio of well-rounded sublattices of the hexagonal lattice of a fixed index.

Distance Coloring of the Hexagonal Lattice [PDF]
Discussiones Mathematicae Graph Theory, 2005 The authors show that the \(d\)-distant chromatic number \(\chi_d(H)\) of the hexagonal lattice \(H\) is (i) \(\chi_d(H)=[\frac 38(d+1)^2]\) for every odd \(d\geq 1\), (ii) \(\frac 38 d^2+\frac 34 d+2\leq\chi_d(H)\leq[\frac 38 (d+\frac 43)^2]\) for every even \(d\geq 8\), where \(\chi_2(H)=4\), \(\chi_4(H)=11\), \(\chi_6(H)=20\).

The hexagonal versus the square lattice [PDF]
Mathematics of Computation, 2003 Schmutz Schaller’s conjecture regarding the lengths of the hexagonal versus the lengths of the square lattice is shown to be true. The proof makes use of results from (computational) prime number theory. Using an identity due to Selberg, it is shown that, in principle, the conjecture can be resolved without using computational prime number theory.
