This workshop focuses on the applications of information theoretic techniques in communication complexity and combinatorics.

Communication complexity studies the communication needed to compute functions whose inputs are distributed across several agents. There are deep connections between communication complexity and other areas of computation, such as circuits, data structures, streaming, space bounded computation, cryptography and optimization. Over the past five years, there have been significant advances in the role of information in the study of communication problems. For example, the role of information complexity and message compression is now much better understood. In the setting of these results, one-shot bounds play a greater role than traditional asymptotic results, and the resulting techniques may be of general interest in the information theory community. Information theoretic techniques have had relatively little success in multiparty communication (as opposed to two-party communication), which presents an opportunity for comparing them with other analytic techniques that have been more successful. In addition, recent work has revived interest in the connection between communication complexity and the existence of linear programming based solutions to optimization problems. This combined body of work, and the open problems there, will form an important component of this workshop. Another component centers on information theoretic lower bounds in streaming and data structures, where there has been an explosion of recent results.

Finally, information theoretic ideas have been employed to study problems in graph theory and combinatorics, notably in counting problems such as counting independent sets in bipartite graphs, Steiner systems, matchings etc. In addition, many results in areas such as hypercontractivity estimates, concentration inequalities and additive combinatorics can be placed in an information theoretic context. This provides scope for useful interactions between experts in information theory and combinatorics.
