Beyond Low-Pass Filters: Adaptive Feature Propagation on Graphs
Sean Li, Dongwoo Kim, Qing Wang
Graph neural networks (GNNs) have been extensively studied for prediction tasks on graphs. As pointed out by recent studies, most GNNs assume local homophily, i.e., strong similari…
The strong geometric lemma for intrinsic Lipschitz graphs in Heisenberg groups
Vasileios Chousionis, Sean Li, Robert Young
We show that the --numbers of intrinsic Lipschitz graphs of Heisenberg groups are locally Carleson integrable when . Our technique relies on a recent Do…
Singular integrals on regular curves in Carnot groups
Vasileios Chousionis, Sean Li, Scott Zimmerman
Let be any Carnot group. We prove that if a convolution type singular integral associated with a -dimensional Calderón-Zygmund kernel is -bounded on horizontal…
Bi-Lipschitz embeddings of Heisenberg submanifolds into Euclidean spaces
Vasileios Chousionis, Sean Li, Vyron Vellis +1
The Heisenberg group equipped with a sub-Riemannian metric is one of the most well known examples of a doubling metric space which does not admit a bi-Lipschitz embedd…
Gâteaux differentiability on infinite-dimensional Carnot groups
Enrico Le Donne, Sean Li, Terhi Moisala
This paper contributes to the generalization of Rademacher's differentiability result for Lipschitz functions when the domain is infinite dimensional and has nonabelian group struc…
The Traveling Salesman Theorem in Carnot Groups
Vasileios Chousionis, Sean Li, Scott Zimmerman
Let be any Carnot group. We prove that, if a subset of is contained in a rectifiable curve, then it satisfies Peter Jones' geometric lemma with some natur…
