This volume collects together research and survey papers written by invited speakers of the
conference celebrating the 70th birthday of László Lovász. The topics covered include classical
subjects such as extremal graph theory coding theory design theory applications of linear
algebra and combinatorial optimization as well as recent trends such as extensions of graph
limits online or statistical versions of classical combinatorial problems and new methods of
derandomization. László Lovász is one of the pioneers in the interplay between discrete and
continuous mathematics and is a master at establishing unexpected connections ¿building
bridges¿ between seemingly distant fields. His invariably elegant and powerful ideas have
produced new subfields in many areas and his outstanding scientific work has defined and
shaped many research directions in the last 50 years. The 14 contributions presented in this
volume all of which are connected to László Lovász's areas of research offer an excellent
overview of the state of the art of combinatorics and related topics and will be of interest to
experienced specialists as well as young researchers.
