On Upper Bounding Shannon Capacity of Graph Through Generalized Conic Programming
Yingjie Bi, Ao Tang
The Shannon capacity of a graph is an important graph invariant in information theory that is extremely difficult to compute. The Lovasz number, which is based on semidefinite prog…
Refined Shapley-Folkman Lemma and Its Application in Duality Gap Estimation
Yingjie Bi, Ao Tang
Based on concepts like kth convex hull and finer characterization of nonconvexity of a function, we propose a refinement of the Shapley-Folkman lemma and derive a new estimate for…
Distributed Synchronization of Heterogeneous Oscillators on Networks with Arbitrary Topology
Enrique Mallada, Randy A. Freeman, Ao Tang
Many network applications rely on the synchronization of coupled oscillators. For example, such synchronization can provide networked devices with a common temporal reference neces…
Skewless Network Clock Synchronization Without Discontinuity: Convergence and Performance
Enrique Mallada, Xiaoqiao Meng, Michel Hack +2
This paper examines synchronization of computer clocks connected via a data network and proposes a skewless algorithm to synchronize them. Unlike existing solutions, which either e…
Synchronization of Weakly Coupled Oscillators: Coupling, Delay and Topology
Enrique Mallada, Ao Tang
There are three key factors of a system of coupled oscillators that characterize the interaction among them: coupling (how to affect), delay (when to affect) and topology (whom to…
