ALGEBRAIC DYNAMICS, SEMINARS
March 30, 2023 4:00 pmLet f(z) be a rational function of degree d>1 over a field K (usually K=C(t) or K=Q), and let x_0 be a point in P^1(K). The Galois groups of the...

SEMINARS, HARVARD-MIT COMBINATORICS
March 29, 2023 4:15 pmStarting with a matroid M one can construct three important algebraic objects: the Chow ring, the augmented Chow ring and the intersection cohomology module. They play instrumental roles within the...

MATHEMATICAL PICTURE LANGUAGE, SEMINARS
March 28, 2023 9:30 amAbstract: A number of problems in analytic number theory can be reduced to showing that some related sequences are non-positive. In this direction a typical treatment is based on the...
