covering of the Calogero-Moser space, we define the notions of left, right and
two-sided Calogero-Moser cells for any finite complex reflection group. To each
Caloger-Moser two-sided... | [

Title: Khovanov complexes of rational tangles,
Abstract: We show that the Khovanov complex of a rational tangle has a very simple
representative whose backbone of non-zero morphisms forms a zig-zag.
Furthermore, this minimal complex can be computed quickly by an inductive
algorithm. (For example, we calculate $Kh(8_2)$... | [

Title: Asymmetric Connectedness of Fears in the U.S. Financial Sector,
Abstract: We study how shocks to the forward-looking expectations of investors buying
call and put options transmit across the financial system. We introduce a new
contagion measure, called asymmetric fear connectedness (AFC), which captures
the inf... | [

Title: Slimness of graphs,
Abstract: Slimness of a graph measures the local deviation of its metric from a tree
metric. In a graph $G=(V,E)$, a geodesic triangle $\bigtriangleup(x,y,z)$ with
$x, y, z\in V$ is the union $P(x,y) \cup P(x,z) \cup P(y,z)$ of three shortest
paths connecting these vertices. A geodesic triang... | [
