Mathematics Subject Classification H compiled and updated by the editorial offices of Math. Sci Mathematics Subject Classification H compiled and updated by the editorial offices of Math. Sci and Zentralblatt MATH. H covers all branches of pure and applied mathematics Pincluding probability and statistics, numerical analysis and computing, mathematical physics and economics, systems theory and control, information and communication theory.

The evolving structure of MSC H From 1959 to 1985 the Math. Sci version The evolving structure of MSC H From 1959 to 1985 the Math. Sci version of MSC counts 60 major sections; 61 from 1986 to 1999 and 63 since 2000. H Until 1972 the classification was issued in two levels; an intermediate level became available in 1973, and is progressively being exploited, as far as MSC increases in detail and so grows in size. H After 1973 major MSC revisions came in use in 1980, 1985, 1986, 1991, 2000. Eighth International Conference "Crimea
