Multi-colour bounded remainder sets
V. G. Zuravlev Vladimir State University
Abstract:
Let r(i,X1)r(i,X1) be the number of points in the SαSα-orbit
of the length ii with respect to a rotation Sα:T1⟶T1 of the unit circle T1=R/Z by an angle α hit the
X1. Denote by δ(i,X1)=r(i,X1)−i|X1| the deviation
of the function r(i,X1) from its average value i|X1|, where
|X1| is the length of X1.
In 1921 E. Hecke had proved the theorem: if X1 has the length
|X1|=hα+b, where h∈N, b∈Z,
then the inequality |δ(i,X1)|⩽h для всех
i=0,1,2,… holds for all i=0,1,2,…
In 1981 г. I. Oren was able to generalize the Hecke theorem to
the case of a finite union of intervals X1. He proved the
estimation δ(i,X1)=O(1) as i→∞.
In the general case, if Xd belongs to the d-dimensional
torus Td=Rd/Zd and there is
δ(i,Xd)=O(1) as i→∞, then Xd is
called a bounded remainder set.
Global approach to search of bounded remainder sets was proposed
by V.G. Zhuravlev in 2011 when, instead of separate sets Xdk
on the torus Td, the complete toric decompositions
Tdc,λ=Xd0⊔Xd1⊔…⊔Xds with parameters c,λ began to be considered. The
main idea was to determine a lifting π−1:Td↪Rd of the torus Td into the
covering space Rd so the rotation Sα maps to
a rearrangement Sv of the corresponding sets
X′0,X′1,…,X′s in Rd.
In the case s+1⩽d+1, each set Xdk=π(X′k) is a bounded
remainder set and the union Tdc,λ=X′0⊔X′1⊔…⊔X′s
in Rd is a toric development for Td.
These developments Td were built with the help of rearrangement
parallelohedra, and the parallelohedra obtained as the Minkowskii
sums of the unit cube Cd and intervals. If d=3,4 we have
the Voronoi parallelohedra and the Fedorov rhombic dodecahedron.
In the present paper, by using tilings of multidimensional tori,
bounded remainder sets are constructed. The tilings consist of a
finite combination of convex polyhedra. A multi-dimension version
of Hecke theorem with respect to the uniform distribution of
fractional parts on the unit circle
is proved for these sets.
