Bounded remainder sets, bounded distance equivalent cut-and-project sets, and equidecomposability

Mark Mordechai Etkind, Sigrid Grepstad, Mihail N. Kolountzakis +1

We use the measurable Hall's theorem due to CieÅla and Sabok to prove that (i) if two measurable sets $A, B \subset R^{d}$ of the same measure are bounded remainder sets wit…

Mark Mordechai Etkind, Nir Lev

An $n \times m$ array with nonnegative entries is called doubly stochastic if the sum of its entries at each row is $m$ and at each column is $n$ . The set of all $n \times m$ doubl…
