the combinatorics group at ucsd covers the full spectrum of modern combinatorics: arithmetic and additive, algebraic and enumerative, extremal and probabilistic. a hallmark of combinatorics is the breadth and depth of its interactions with other subjects; faculty in our group pursue research with exciting links to algebraic geometry, differential equations, harmonic analysis, mathematical physics, number theory, probability theory, representation theory and theoretical computer science.
 
our group provides an active and stimulating environment for graduate 2022年亚洲世界杯预选赛 . we host a weekly seminar, consistently offer a range of graduate course sequences in core combinatorial disciplines, and regularly teach advanced topics courses and reading courses. 

during the last fifteen years, ucsd combinatorics has been among the top six in the us news ranking of phd programs in discrete mathematics and combinatorics - it currently ranks 5th in the nation in this category.
