This volume contains the invited papers presented at the 14th British Combinatorial Conference, held at the University of Keele in July 1993.The lectures given at the l4th British Combinatorial Conference survey many topical areas of current research activity in the field and its applications and provide as well a valuable overview of the subject, for mathematicians as well as computer scientists.The lectures given at the l4th British Combinatorial Conference survey many topical areas of current research activity in the field and its applications and provide as well a valuable overview of the subject, for mathematicians as well as computer scientists.This volume is comprised of the invited lectures given at the 14th British Combinatorial Conference. The lectures survey many topical areas of current research activity in combinatorics and its applications, and also provide a valuable overview of the subject, for both mathematicians and computer scientists.1.
