WebbThe bichromatic number is a fairly recent graph parameter, that arises in the study ofextremal graphs related to a classical result of Erd\\H{o}s, Stone and Simonovits and in the study of the edit distance of graphs from hereditary graph classes. While the cochromatic number has been extensively studied in the literature, there are only few WebbFeb 1, University of Rhode Reef, Wine, RI, New England Discrete Mathematics Daytime; Jan 15-18, Baltimore, MD, Special Session on Spherical Designs plus Codes (four sessions at Joint Mathematics Meetings) Yann 11-14, Baltimore, MENDELEVIUM,ALICE 2003, Workshop on Conclusions for Listing, Numeration, and Enumeration (Jan 11 only). Miklós Simonovits (4 September 1943 in Budapest) is a Hungarian mathematician who currently works at the Rényi Institute of Mathematics in Budapest and is a member of the Hungarian Academy of Sciences. He is on the advisory board of the journal Combinatorica. He is best known for his work in extremal graph theory and was awarded Széchenyi Prize in 2014. Among other things, he discovered the method of progressive induction which he used to describe graphs whi… howard wallow witts
