GALaC organizes or participates in three different regular seminars.

GALaC team seminar

The GALaC team seminar is organized once a month on Friday at 14:30 in the Ada Lovelace building at LRI. Recent and up-coming seminars

Plateau Saclay Combinatorics Seminar

The Plateau Saclay Combinatorics Seminar is held every Wednesday morning at 11 AM in room Flajolet (top floor on the left) at LIX. It is co-organized by the Combi team of LIX and the GALaC team. The mailing list for this seminar is Subscribe to this ...

Plateau Saclay Algorithms Seminar

The Plateau Saclay Algorithms Seminar is held every other Friday afternoon in LIX. This working group is partially supported by Labex DigiCosme (Digital worlds: distributed data, programs and architectures). If you do wish (or not) to receive any emails from this seminar, you can subscribe or unsubscribe from the mailing ...

Binary pattern of length greater than 14 are abelian-2-avoidable

-- Matthieu Rosenfeld (GALAC, LRI)

Summary: Two words u and v are abelian equivalent if they are permutation of each other ("aabc" and "baca" are abelian equivalent). Let w be a word and P= P1...Pn (where the Pi are the letters of P) a pattern (a word over another alphabet), we say that w ...

Cyclic sieving for reduced reflection factorizations of the Coxeter element

-- Theo Douvropoulos (IRIF, Paris 7 Diderot)

Given a factorization \(t_1\cdots t_n=c\) of some element \(c\) in a group, there are various natural cyclic operations we can apply on it; one of them is given by \(\Psi:(t_1,\cdots,t_n)\rightarrow (c\ t_n\ c^{-1},t_1,\cdots, t_{n-1})\). A common question is then to ...

Caractérisation de réseaux égocentrés par l'énumération de leurs sous-graphes induits

-- Raphaël Charbey (GALAC, LRI)

Résumé : La science des réseaux regroupe des méthodes issues de différentes disciplines qui ont néanmoins souvent du mal à percer au delà de celles-ci. Très utilisée en biologie moléculaire, notamment dans le cadre de l'étude des interactions entre protéines, l'énumération de l'ensemble des sous-graphes induits, jusqu'à ...
