Algorithm Support for Graph Databases, Done Right
Daan de Graaf, Robert Brijder, Soham Chakraborty +3
Graph database query languages cannot express algorithms like PageRank, forcing costly data wrangling, while existing solutions such as algorithm libraries, vertex-centric APIs, an…
Kesten's criterion for discrete probability measure-preserving groupoids
Soham Chakraborty, Milan Donvil, Felipe Flores +1
Inspired by Kesten's criterion for the amenability of groups, we establish a characterization of the amenability of discrete probability measure-preserving groupoids in terms of th…
On ergodicity of linear actions on and factoriality of group von Neumann algebras
Soham Chakraborty, Chinmay Tamhankar
We give some natural conditions on actions of discrete countable groups on abelian locally compact groups of Lie type that imply factoriality of the group von Neumann algebras of t…
Factoriality of groupoid von Neumann algebras
Tey Berendschot, Soham Chakraborty, Milan Donvil +1
We give a characterisation of factoriality of the groupoid von Neumann algebra associated to a discrete measured groupoid . We introduce the noti…
