Distance flexibility in spatial matching: the value of concentration
Taha Ameen, Sophie H. Yu
In spatial matching markets, a supply unit's flexibility is measured by its service radius, the maximum distance at which it can serve demand. In dimensions , we study ho…
Converse bounds for multiple graph alignment and correlation detection based on last matching
Taha Ameen, Bruce Hajek
The paper focuses on information theoretic converse bounds for the alignment of correlated graphs and for the detection of correlation among graphs. A simple idea for $m\ge…
Estimating Community Boundaries in Geometric Random Graphs
Taha Ameen, Neeladri Maitra
The unit square is divided into two rectangles by the vertical line , where . Consider independent uniformly distributed points on , which we int…
Optimality of a Threshold Policy for a Queueing System with One Fast Server and Two Identical Slow Servers
Weina Wang, Taha Ameen, Yudong Chen +3
This paper studies the optimal control problem of a queueing system with three servers: one fast server and two identical slow servers. The two-server version of this problem, with…
Flexibility allocation in random bipartite matching markets: exact matching rates and dominance regimes
Taha Ameen, Flore Sentenac, Sophie H. Yu
This paper studies how a fixed flexibility budget should be allocated across the two sides of a balanced bipartite matching market. We model compatibilities via a sparse bipartite…
A uniformity principle for spatial matching
Taha Ameen, Flore Sentenac, Sophie H. Yu
Platforms matching spatially distributed supply to demand face a fundamental design choice: given a fixed total budget of service range, how should it be allocated across supply no…
Detecting Planted Structure in Circular Data
Taha Ameen, Bruce Hajek
Hypothesis testing problems for circular data are formulated, where observations take values on the unit circle and may contain a hidden, phase-coherent structure. Under the null,…
Sharp Detection Threshold for Correlation among Multiple Unlabeled Gaussian Networks
Taha Ameen, Bruce Hajek
This paper studies the hypothesis testing problem of deciding whether complete weighted graphs with Gaussian edge weights are mutually correlated after unknown relabelin…
Aligning Multiple Inhomogeneous Random Graphs: Fundamental Limits of Exact Recovery
Taha Ameen, Bruce Hajek
This work studies fundamental limits for recovering the underlying correspondence among multiple correlated graphs. In the setting of inhomogeneous random graphs, we present and an…
Robust Graph Matching when Nodes are Corrupt
Taha Ameen, Bruce Hajek
Two models are introduced to investigate graph matching in the presence of corrupt nodes. The weak model, inspired by biological networks, allows one or both networks to have a pos…
Blockchain Security when Messages are Lost
Taha Ameen, Suryanarayana Sankagiri, Bruce Hajek
Security analyses for consensus protocols in blockchain research have primarily focused on the synchronous model, where point-to-point communication delays are upper bounded by a k…
Slit-strip Ising boundary conformal field theory 2: Scaling limits of fusion coefficients
Taha Ameen, Kalle Kytölä, S. C. Park
This is the second in a series of three articles about recovering the full algebraic structure of a boundary conformal field theory (CFT) from the scaling limit of the critical Isi…
Computing Robust Forward Invariant Sets of Multidimensional Non-linear Systems via Geometric Deformation of Polytopes
Taha Ameen, Shayok Mukhopadhyay, Nasser Qaddoumi
This paper develops and implements an algorithm to compute sequences of polytopic Robust Forward Invariant Sets (RFIS) that can parametrically vary in size between the maximal and…
Slit-strip Ising boundary conformal field theory 1: Discrete and continuous function spaces
Taha Ameen, Kalle Kytölä, S. C. Park +1
This is the first in a series of articles about recovering the full algebraic structure of a boundary conformal field theory (CFT) from the scaling limit of the critical Ising mode…
