When is a function from an abelian group to itself expressible as a difference of two bijections? Answering this question for finite cyclic groups solves a problem about juggling.

20th Annual Symposium on Foundations of Computer Science (sfcs 1979), 1979
In this paper we study bijective a-transducers. We derive necessary and sufficient conditions on pairs of regular sets (R,S) such that a bijective a-transducer, mapping R cnto S exists. The results obtained allow the systematic construction of an a-transducer, mapping a set R onto a set S bijectively for surprisingly "different" regular sets R and S.

Bijective projection in a shell
ACM Transactions on Graphics, 2020We introduce an algorithm to convert a self-intersection free, orientable, and manifold triangle mesh T into a generalized prismatic shell equipped with a bijective projection operator to map T to a class of discrete surfaces contained within the shell whose normals ...

Efficient bijective parameterizations
ACM Transactions on Graphics, 2020We propose a novel method to efficiently compute bijective parameterizations with low distortion on disk topology meshes. Our method relies on a second-order solver. To design an efficient solver, we develop two key techniques. First, we propose a coarse shell to substantially reduce the number of collision constraints that are used to ...

A bijection between ordered trees and bicoloured ordered trees [PDF]
Discrete Mathematics, 2009 A bijection is introduced between ordered trees and bicoloured ordered trees, which maps leaves in an ordered tree to odd height vertices in the related tree.

Two problems, connected with analysing empirical data are considered. First is a problem of minimizing the number of crossings in a bipartite graph. Second is a pattern matching problem for permutations. In both cases the original problem is transformed into a similar problem for an appropriate mathematical structure, which can be considered as an ...
