Arithmetic Properties of 1–shell Totally Symmetric Plane Partitions
In 2012, Blecher defined the combinatorial objects known as 1–shell totally symmetric plane partitions of weight n. He also proved that the generating function for f (n), the number of 1–shell totally symmetric plane partitions of weight n, is given by ∑
متن کاملCombinatorics of Integer Partitions in Arithmetic Progression
The partitions of a positive integer n in which the parts are in arithmetic progression possess interesting combinatorial properties that distinguish them from other classes of partitions. We exhibit the properties by analyzing partitions with respect to a fixed length of the arithmetic progressions. We also address an open question concerning the number of integers k for which there is a k-par...
متن کاملRandom Sampling of Plane Partitions
This article presents uniform random generators of plane partitions according to the size (the number of cubes in the 3D interpretation). Combining a bijection of Pak with the method of Boltzmann sampling, we obtain random samplers that are slightly superlinear: the complexity is O(n(lnn)3) in approximate-size sampling and O(n4/3) in exact-size sampling (under a real-arithmetic computation mode...
متن کاملTsallis Entropy and Conditional Tsallis Entropy of Fuzzy Partitions
The purpose of this study is to define the concepts of Tsallis entropy and conditional Tsallis entropy of fuzzy partitions and to obtain some results concerning this kind entropy. We show that the Tsallis entropy of fuzzy partitions has the subadditivity and concavity properties. We study this information measure under the refinement and zero mode subset relations. We check the chain rules for ...
متن کاملPlane Partitions
Throughout our study of the enumeration of plane partitions we make use of bijective proofs to find generating functions. In particular, we consider bounded plane partitions, symmetric plane partitions and weak reverse plane partitions. Using the combinatorial interpretations of Schur functions in relation to semistandard Young tableaux, we rely on the properties of symmetric functions. In our ...
