چکیده

It follows from work of Andrews and Bressoud that for t the number of partitions of n with all successive ranks at least t is equal to the number of partitions of n with no part of size t However no simple combinatorial explanation of this fact has appeared in the literature We give a simple bijection for this identity which generalizes a result of Cheema and Gordon for rowed plane partitions The bijection yields several re nements of the identity when the partition counts are parametrized by the minimum successive rank the number of parts and or the size of the Durfee rectangle In addition it gives a natural interpretation of the di erence of shifted successive Gaussian polynomials which we relate to other interpretations of Andrews and Fishel

A Bijection for Partitions with All Ranks at Least tSylvie

It follows from work of Andrews and Bressoud that for t 1, the number of partitions of n with all successive ranks at least t is equal to the number of partitions of n with no part of size 2?t. We give a simple bijection for this identity which generalizes a result of Cheema and Gordon for 2-rowed plane partitions. The bijection yields several reenements of the identity when the partition count...

Jagged partitions and lattice paths

A lattice-path description of K-restricted jagged partitions is presented. The corresponding lattice paths can have peaks only at even x coordinate and the maximal value of the height cannot be larger than K − 1. Its weight is twice that of the corresponding jagged partitions. The equivalence is demonstrated at the level of generating functions. A bijection is given between K-restricted jagged ...

A lattice path approach to counting

In this paper we give a combinatorial proof via lattice paths of the following result due to Andrews and Bressoud: for t 1, the number of partitions of n with all successive ranks at least t is equal to the number of partitions of n with no part of size 2 ? t. The identity is a special case of a more general theorem proved by Andrews and Bressoud using a sieve.
