On -blocks with quaternion defect groups
Charles Eaton, Florian Eisele, Radha Kessar +2
We determine the Morita equivalence classes of -blocks with quaternion defect groups of arbitrary -power order, thereby completing the proof of Donovan's conjecture for block…
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…
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,…
