The Kazhdan-Lusztig polynomial of a matroid
... braid matroid. Polo [Pol99] has shown that any polynomial with non-negative coefficients and constant term 1 appears as a Kazhdan-Lusztig polynomial associated to some symmetric group, while Kazhdan-Lusztig polynomials of matroids are far more restrictive (see Proposition 2.14). The original work of ...

... semester or Section 7.7 in Artin). We show that in this ring, multiplication is the usual multiplication mod 15. However, 3 · 5 ≡ 0 mod 15. This is a particular instance of the more general fact that the ring Z/(n) is an integral domain if and only if n is prime. (b) Let I ⊂ R be an ideal. Prove tha ...
