The Banff International Research Station will host the "Invariants of Incidence Matrices” workshop next week, March 29 - April 3, 2009.

Incidence matrices are rectangular arrays of zeros and ones in which the columns and rows represent two sets of objects and the occurrence of a one in a certain row and column indicates a relation between the corresponding row object and column object. The study of incidence matrices is fundamental to several areas of algebra and combinatorics and also has applications in statistics to the design of experiments and in electrical engineering to the reliable transmission and storage of data.

The Banff International Research Station for Mathematical Innovation and Discovery (BIRS) is a collaborative Canada-US-Mexico venture that provides an environment for creative interaction as well as the exchange of ideas, knowledge, and methods within the Mathematical Sciences, with related disciplines and with industry. The research station is located at The Banff Centre in Alberta and is supported by Canada's Natural Science and Engineering Research Council (NSERC), the US National Science Foundation (NSF), Alberta's Advanced Education and Technology, and Mexico's Consejo Nacional de Ciencia y Tecnologí­a (CONACYT).
