Parallel Rank of Two Sandpile Models of Signed Integer Partitions
Keyword(s):
We introduce the concept of fundamental sequence for a finite graded posetXwhich is also a discrete dynamical model. The concept of fundamental sequence is a refinement of the concept of parallel convergence time for these models. We compute the parallel convergence time and the fundamental sequence whenXis the finite lattice of all the signed integer partitions such that , where , and whenXis the sublattice of all the signed integer partitions of having exactlydnonzero parts.
