Existence of a Nonsmoothable Local Gorenstein Algebra with Smoothable Q(0)
Ruoyu Wu
We prove that there exists a local Artinian Gorenstein algebra \(A\) which is not smoothable, although the first symmetric quotient \(Q_A(0)\) in the symmetric decomposition of the…

Many-Server Asymptotics for Join-the-Shortest-Queue: Large Deviations and Rare Events
Amarjit Budhiraja, Eric Friedlander, Ruoyu Wu
The Join-the-Shortest-Queue routing policy is studied in an asymptotic regime where the number of processors scales with the arrival rate. A large deviation principle (LDP) for…
