The study describes a cell structure for multisets in a rectangle.
Aguiar and Ardila defined the Hopf monoid GP of generalized permutahedra and showed that it contains many submonoids that correspond to combinatorial objects. They also give a basic polynomial invariant of generalized permutahedra, which then specializes to the submonoids. We define the Hopf monoid of directed graphs a…
The paper studies splitting maps in link Floer homology using skein exact sequences.
