DESCRIPTION:Title: New types of heights with connections to the Batyrev-Manin and Malle Con
jectures\nby Matthew Satriano (University of Waterloo) as part of Alge
bra\, Geometry\, and Combinatorics\n\n\nAbstract\nThe Batyrev-Manin conjec
ture gives a prediction for the asymptotic growth rate of rational points
on varieties over number fields when we order the points by height. The Ma
lle conjecture predicts the asymptotic growth rate for number fields of de
gree d when they are ordered by discriminant. The two conjectures have the
same form and it is natural to ask if they are\, in fact\, one and the sa
me. We develop a theory of point counts on stacks and give a conjecture fo
r their growth rate which specializes to the two aforementioned conjecture
s. This is joint work with Jordan Ellenberg and David Zureick-Brown. No pr
ior knowledge of stacks will be assumed for this talk.\n

DESCRIPTION:Title: Convexity in tropical spaces and compactifications of cluster varieties<
/a>\nby Timothy Magee (University of Birmingham) as part of Algebra\, Geom
etry\, and Combinatorics\n\n\nAbstract\nCluster varieties are a relatively
new\, broadly interesting class of geometric objects that generalize tori
c varieties. Convexity is a key notion in toric geometry. For instance\,
projective toric varieties are defined by convex lattice polytopes. In t
his talk\, I'll explain how convexity generalizes to the cluster world\, w
here "polytopes" live in a tropical space rather than a vector space and "
convex polytopes" define projective compactifications of cluster varieties
. Time permitting\, I'll conclude with two exciting applications of this
more general notion of convexity: 1) an intrinsic version of Newton-Okounk
ov bodies and 2) a possible cluster version of a classic toric mirror symm
etry construction due to Batyrev. Based on joint work with Man-Wai Cheung
and Alfredo Nájera Chávez.\n

DESCRIPTION:Title: Quotients of lattice path matroids\nby Carolina Benedetti (Universi
dad de los Andes) as part of Algebra\, Geometry\, and Combinatorics\n\n\nA
bstract\nMatroids are a combinatorial object that generalize the notion of
linear independence. One way to characterize matroids is via polytopes\,
as shown in the work of Gelfand\, Goresky\, MacPherson\, Serganova. \n\nIn
this talk we will focus on a particular class of matroids called Lattice
Path Matroids (LPMs). We will show when a collection M_1\,...\,M_k of LPMs
are a flag matroid\, using their combinatorics. Part of our work will sho
w that the polytope associated to such a flag can be thought as an interva
l in the Bruhat order\, and thus provides a partial understanding of flags
of LPMs from a polytopal point of view. \n\nWe will not assume previous k
nowledge on matroids nor quotients. This is joint work with Kolja Knauer.\
