Seminars
GALaC organizes or participates in three different regular seminars.
GALaC team seminar
The GALaC team seminar is organized on a regular basis on Friday at 14:00 in the PCRI building (650) at LISN. Recent and up-coming seminars
Plateau Saclay Combinatorics Seminar
The Plateau Saclay Combinatorics Seminar is held on several Mondays at 11am in room Philippe 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 combi_lix_lri@services.cnrs.fr. 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 ...
Compléter des colorations partielles de hom shifts
summary: On étudie les shifts ou espaces de pavages de type fini : des colorations de la grille régulière infinie qui évitent un ensemble fini de motifs interdits. Il s'agit d'un modèle étudié en particulier comme source apparemment infinie de problèmes indécidables.
Les hom shifts sont une restriction du ...

Skeletal posets of the Tamari lattice and beyond
summary: Given a lattice \(L\), the subposet \(\mathrm{Spine}(L)\) of \(L\) is the union of the longest maximal chains in \(L\). Dually, the subposet \(\mathrm{Spine}'(L)\) of \(L\) is the union of the shortest maximal chains in \(L\). For certain lattices, these subposets are particularly well-behaved; an example ...
