Nir Gadish

We define invariants of words in arbitrary groups, measuring how letters in a word are interleaving, perfectly detecting the dimension series of a group. These are the letter-braid…

A Serre spectral sequence for the moduli space of tropical curves

Christin Bibby, Melody Chan, Nir Gadish +1

We construct, for all $g \geq 2$ and $n \geq 0$ , a spectral sequence of rational $S_{n}$ -representations which computes the $S_{n}$ -equivariant reduced rational cohomology of the tropica…
