Shrinking target problems for flows on homogeneous spaces
The shrinking target problem for diagonalizable flows on a homogeneous space is well understood due to the work of Kleinbock and Margulis. The main ingredients for the proof are a quantitative Borel-Cantelli lemma and the exponential decay of matrix coefficients for digaonalizable flows. Much less is known for unipotent flows. In this talk, I will discuss a much weaker decay condition which ensures the quantitative Borel-Cantelli lemma and apply this result to unipotent flows. This is joint work with Dubi Kelmer.

Enumeration of paths via occurrences of distinguished strings and a proof of Touchard’s identity
We will count paths by occurrences of several strings of steps in Dyck paths. There is an extensive literature on lattice path enumeration where authors count the occurrence of a particular string in Dyck paths, sometimes also keeping track of whether such a string occurs at even or odd height. This has been done, for example, by Deutsch in "Dyck path enumeration, Discrete Math. 204 (1999), no. 1-3, 167--202." There "peaks", "valleys", and "doublerises" are studied and as a result give Narayana numbers. Strings of length 3 are also considered by Deutsch. The authors of "A. Sapounakis, I. Tasoulas, and P. Tsikouras, Counting strings in Dyck paths, Discrete Mathematics 307 (2007), no. 23, 2909--2924." count paths by occurrences of any given string of length 4 and by semilength. In this talk we count three types of substrings simultaneously which together also count paths by semilength and number of peaks. Special cases of this enumeration give several well-known families of numbers such as Catalan, Motzkin, Narayana, and Schröder numbers. We will also give a short proof of Touchard's identity via colored Motzkin paths.

Topology Seminar

Decomposing Cube Complexes
It is known that if a group acts nicely on a product of CAT(0) cube complexes, then the group must virtually decompose as a product of groups. In this talk, we will discuss when the opposite is true: given a nice action of a product of groups on a CAT(0) cube complex, when can we say that the cube complex decomposes as a product of cube complexes?

A bijective approach to percolation on random lattices, and maybe more
I will talk about planar maps and percolation. I will show that planar triangulations endowed with a percolation configuration can be bijectively encoded by certain lattice paths in the quarter plane. I will explain what can be done using this bijection. Time permitting I will also talk about some big conjectures in 2D random geometries (about the relation between the Gaussian free field, SLE curves, and Brownian surfaces), and how the bijection may be instrumental in proving them. This is a joint work with Nina Holden and Xin Sun.

Generalized loop Grassmannians
Loop Grassmannians appear in the geometric Langlands program as a geometrization of Hecke operators in number theory. They are also "the simplest'' noncommutative cohomology objects in algebraic geometry. We will reconstruct the loop Grassmannian of a reductive group in terms of an elementary mechanism of ``local spaces''. This is just another mathematical model of collision of particles, a version of the Beilinson-Drinfeld notion of factorization spaces or the Feigin-Loktev fusion of representations etc. This construction actually provides a larger class of spaces generalizing the known loop Grassmannians.
