Unbalanced Minimal Matchings for Measurable Scale Invariant Costs on
Omer Angel, Nitya Gadhiwala
Given red and blue points drawn from Poisson point processes of equal intensities, we match them by locally minimizing a cost function. In our paper, we identify all possible measu…
Trajectory inference for a branching SDE model of cell differentiation
Elias Ventre, Aden Forrow, Nitya Gadhiwala +3
A core challenge for modern biology is how to infer the trajectories of individual cells from population-level time courses of high-dimensional gene expression data. Birth and deat…
Random walks on regular trees can not be slowed down
Omer Angel, Jacob Richey, Yinon Spinka +1
A random walk on a regular tree (or any non-amenable graph) has positive speed. We ask whether such a walk can be slowed down by applying carefully chosen time-dependent permutatio…
Uniform even subgraphs and graphical representations of Ising as factors of i.i.d
Omer Angel, Gourab Ray, Yinon Spinka
We prove that the Loop O(1) model, a well-known graphical expansion of the Ising model, is a factor of i.i.d. on unimodular random rooted graphs under various conditions, including…
Amenability of quadratic automaton groups
Gideon Amir, Omer Angel, Balint Virag
We give lower bounds for the electrical resistance between vertices in the Schreier graphs of the action of the linear (degree 1) and quadratic (degree 2) mother groups on the orbi…
Dynamical noise sensitivity for the voter model
Gideon Amir, Omer Angel, Rangel Baldasso +1
We study noise sensitivity of the consensus opinion of the voter model on finite graphs, with respect to noise affecting the initial opinions and noise affecting the dynamics. We p…
