In this presentation, I will briefly talk about the problems I have been working on in collaboration with several leading researchers in the past 5 months in the Institute of Network Coding. I will begin by talking about a technique for proving converses to the network coding problem with correlated sources based on “uncertainty computations”, and show how one can strictly improve over the traditional cut set bound. This is a joint work with Dr. Yang, Prof. Jaggi and Prof. Yeung. Then I will summarize a collection of results that Prof. Nair, I and two of Prof. Nair’s students have on the general broadcast channel. These include finding the capacity region of new classes of broadcast channels, answering an important open problem regarding the best known outer bound, and several other results and insights which enhance our understanding of the broadcast channels.
