Analytic ideals form a bridge between descriptive set theory and combinatorial topology by encapsulating infinite combinatorial structures within well-behaved collections of subsets. At their core, ...

The American Mathematical Society has awarded its 2019 Leroy P. Steele Prize for Mathematical Exposition to Robert Sedgewick, Princeton’s William O. Baker *39 Professor in Computer Science, and ...

Combinatorial structures encompass an array of discrete objects—permutations, set partitions, matchings, trees and lattice paths—whose enumeration and intrinsic properties are often captured by ...
