Coding Partitions of Regular Sets
A coding partition of a set of words partitions this set into classes such that whenever a sequence, of minimal length, has two distinct factorizations, the words of these factorizations belong to the same class. The canonical coding partition is the finest coding partition that partitions the set of words in at most one unambiguous class and other classes that localize the ambiguities in the f...
متن کاملSets, Lists and Noncrossing Partitions
Partitions of [n] = {1, 2, . . . , n} into sets of lists are counted by sequence A000262 in the On-Line Encyclopedia of Integer Sequences. They are somewhat less numerous than partitions of [n] into lists of sets, A000670. Here we observe that the former are actually equinumerous with partitions of [n] into lists of noncrossing sets and give a bijective proof. We show too that partitions of [n]...
متن کاملOn Sets Represented by Partitions
We prove a lemma that is useful to get upper bounds for the number of partitions without a given subsum. From this we can deduce an improved upper bound for the number of sets represented by the (unrestricted or into unequal parts) partitions of an integer n.
متن کاملSets, Partitions and Functions Interpolations
This paper presents the use of the SKIZ transformation to interpolate sets, partitions and functions. This transformation generates a sequence of intermediary sets which can be used to de ne a distance between the interpolated sets. Other distances are also introduced. These distances could be useful to generalise the interpolation algorithm. Some examples of use are given.
متن کاملOn Conjugation Partitions of Sets of Trinucleotides
We prove that a trinucleotide circular code is self-complementary if and only if its two conjugated classes are complement of each other. Using only this proposition, we prove that if a circular code is self-complementary then either both its two conjugated classes are circular codes or none is a circular code.
