WG 1: Bounds on the Size of Network Codes
Chairs: Tuvi Etzion, Joachim Rosenthal
Work programme
Traditional algebraic coding theory is aware of a number of existence bounds for linear and non-linear error-correcting codes. Among the restrictive examples of bounds, one has to mention the Plotkin and Elias-Bassalygo bound, the sphere-packing bound, the Singleton bound, whereas bounds like the Gilbert-Varshamov bound and the BCH-bound are assertive and often provide construction mechanisms for good codes. This Working Group will focus on the mathematical task to formulate and prove amended versions of traditional bounds, or to provide new bounds for network codes. From possible assertive bounds it is expected that new construction methods will be provided to the benefit of the work in Working Group 4.
