Repetitions in Strings
Prof. Maxime Crochemore,
Université Paris-Est, France –
Large amounts of text are generated every day in the cyberspace
via Web sites, emails, social networks, and other communication
networks. These text streams need to be analysed to detect critical
events or the monitor business for example.
An important characteristics to take into account in this setting
is the existence of repetitions in texts. Their study constitutes
a fundamental area of combinatorics on words due to major applications
to string algorithms, data compression, music analysis, and biological
sequences analysis, etc.
The talk surveys algorithmic methods used to locate repetitive
segments in strings. It discusses the notion of runs that encompasses
various types of periodicities considered by different authors, as well
as the notion of maximal-exponent factors that captures the most
significant repeats occurring in a string.
The design and analysis of repeat finders rely on combinatorial
properties of words and raise a series of open problems in
combinatorics on words.
Prof. Maxime Crochemore received his PhD in 1978 and his Doctorat
(DSc) in 1983 at the University of Rouen. He got his first professorship
position at the University of Paris-Nord in 1985 where he acted as
President of the Department of Mathematics and Computer Science for two
years. He became professor at the University Paris 7 in 1989 and was
involved in the creation of the University of Marne-la-Valle where he is
Professor, Emeritus from 2007. He also created the Computer Science
research laboratory of this university in 1991 and was the director until
2005. He was Deputy Scientific Director of the Information and
Communication Department of CNRS from 2004 to 2006. He was Senior Research
Fellow from 2002 to 2007 and is presently Professor at King’s College
London. Prof. Crochemore’s research interests are in the design and
analysis of algorithms.
His major achievements are on string algorithms, which includes pattern
matching, text indexing, coding, and text compression. He also works on
the combinatorial background of these subjects and on their applications
to bio-informatics. He has co-authored several textbooks on algorithms and
published more than 200 articles. He has been the recipient of several
French grants on string algorithms and bio-informatics. He participated in
a good number of international projects on algorithms and supervised to
completion more than twenty PhD students.

Workshop “Metabolism and mathematical models: Two for a tango” – 2nd Edition
Title: Workshop Metabolism and mathematical models: Two for a tango – 2nd Edition
Dates: October 25-26, 2022
Location: This workshop will be held in a virtual way
The topic of this workshop is metabolism in general, with a special focus, although not exclusive, on parasitology. Besides an exploration of the biological, biochemical and biomedical aspects, the workshop will also aim at presenting some of the mathematical modelling, algorithmic theory and software development that have become crucial to explore such aspects.
This workshop is being organised in the context of two projects, both with the Inria European Team Erable. One of the projects involves a partnership with the University of São Paulo (USP), in São Paulo, Brazil, more specifically the Institute of Mathematics and Statistics (IME) and the Institute of Biomedical Sciences – Inria Associated Team Capoeira – and the other involves the Inesc-ID/IST in Portugal, ETH in Zürich and EMBL in Heidelberg – H2020 Twinning Project Olissipo.
The workshop is open to all members of these two projects but also, importantly, to the community in general.
The program and more details are available here.
