A Rogers-Ramanujan bijection [PDF]

open access: yesJournal of Combinatorial Theory, Series A, 1981
AbstractIn this paper we give a bijection between the partitions of n with parts congruent to 1 or 4 (mod 5) and the partitions of n with parts differing by at least 2. This bijection is obtained by a cut-and-paste procedure which starts with a partition in one class and ends with a partition in the other class.

A bijection for nonorientable general maps [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2020
We give a different presentation of a recent bijection due to Chapuy and Dołe ̨ga for nonorientable bipartite quadrangulations and we extend it to the case of nonorientable general maps.

A Bijection for Enriched Trees [PDF]

open access: yesEuropean Journal of Combinatorics, 1994
The author establishes a bijection involving species of enriched trees that leads to a combinatorial proof of Lagrange's inversion formula.

A bijection between permutations and a subclass of TSSCPPs [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2013
We define a subclass of totally symmetric self-complementary plane partitions (TSSCPPs) which we show is in direct bijection with permutation matrices. This bijection maps the inversion number of the permutation, the position of the 1 in the last column,

A Bijection for Tricellular Maps

open access: yesISRN Discrete Mathematics, 2013
We give a bijective proof for a relation between unicellular, bicellular, and tricellular maps. These maps represent cell complexes of orientable surfaces having one, two, or three boundary components. The relation can formally be obtained using matrix theory (Dyson, 1949) employing the Schwinger-Dyson equation (Schwinger, 1951).

A Bijection for Directed-Convex Polyominoes [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2001
In this paper we consider two classes of lattice paths on the plane which use \textitnorth, \textiteast, \textitsouth,and \textitwest unitary steps, beginningand ending at (0,0).We enumerate them according to the number ofsteps by means of bijective ...

Synthesizing bijective lenses [PDF]

open access: yesProceedings of the ACM on Programming Languages, 2017
Bidirectional transformations between different data representations occur frequently in modern software systems. They appear as serializers and deserializers, as parsers and pretty printers, as database views and view updaters, and as a multitude of different kinds of ad hoc data converters. Manually building bidirectional transformations---by writing
