Contributions edit
In combinatorics, Pollack published several papers with Paul Erdős and János Pach.[4][5][6][7]
Pollack also published papers in discrete geometry.[8][9][10][11][12][13][14][15][16][17][18] His work with Jacob E. Goodman includes the first nontrivial bounds on the number of order types and polytopes,[8] and a generalization of the Hadwiger transversal theorem to higher dimensions.[9] He and Goodman were the founding editors of the journal Discrete & Computational Geometry.[19]
In real algebraic geometry, Pollack wrote a series of papers with Saugata Basu and Marie-Françoise Roy,[13][14][15][16] as well as a book.[20]
Awards and honors edit
In 2003, a collection of original research papers in discrete and computational geometry entitled Discrete and Computational Geometry: The Goodman–Pollack Festschrift was published as a tribute to Jacob E. Goodman and Richard Pollack on the occasion of their 2/3 × 100 birthdays.[21]
In 2012, he became a fellow of the American Mathematical Society.[22]
A special memorial 556-page issue of Discrete & Computational Geometry for Pollack was published in October 2020.[23]
