Surveys in Combinatorics, 1989: Invited Papers at the Twelfth British Combinatorial Conference (London Mathematical Society Lecture Note Series)

Many areas of current research activity in combinatorics and its applications, including graph theory, designs and probabilistic graphs, are surveyed in lectures presented at the 12th British Combinatorial Conference. This volume contains the invited lectures given at the Twelfth British Combinatorical Conference. The lectures survey the many areas of current research activity in combinatorics and its applications, including graph theory, designs, and probabilistic graphs. This book provides a valuable survey of the present status of knowledge in combinatorics for mathematicians, computer scientists and engineers. Several years ago I was asked a seemingly innocuous question: What are the minimal-weight vectors of the code of an affine plane?
