The necklace Lie coalgebra and renormalization algebras
Wee Liang Gan, Travis Schedler
We give a natural monomorphism from the necklace Lie coalgebra, defined for any quiver, to Connes and Kreimer's Lie coalgebra of trees, and extend this to a map from a certain quiv…

Concrete and abstract structure of the sandpile group for thick trees with loops
William Chen, Travis Schedler
We answer a question of Laszlo Babai concerning the abelian sandpile model. Given a graph, the model yields a finite abelian group of recurrent configurations which is closely rela…
