SUMMARY:Miklos Bona\, University of Florida
STATUS:CONFIRMED
DESCRIPTION:In evolutionary biology\, a genome can be represented by a perm
utation\, with the entries of the permutation playing the role of genes. T
he evolutionary distance between two species can be defined as the minimum
number of transformations of a certain kind that can turn the genome of o
ne species into the genome of another.\n\nIt is easy to reduce this distan
ce-measuring problem into a sorting problem. That is\, given a permutation
\, let us turn it into the identity permutation using some allowed steps.
This raises a family of questions that are interesting\, difficult\, and l
ead to very surprising discoveries. They would be interesting even without
the biological motivation as they touch on remote-looking areas of combin
atorics\, group theory\, and algebra. \n\nIn this talk\, we will survey re
sults and intriguing open problems that are typical in this field. Only an
undergraduate knowledge of combinatorics will be assumed.
