A homology valued invariant for trivalent fatgraph spines

Yusuke Kuno

We introduce an invariant for trivalent fatgraph spines of a once bordered surface, which takes values in the first homology of the surface. This invariant is the secondary object…

Generalized Kronecker formula for Bernoulli numbers and self-intersections of curves on a surface

Shinji Fukuhara, Nariya Kawazumi, Yusuke Kuno

We present a new explicit formula for the $m$ -th Bernoulli number $B_{m}$ , which involves two integer parameters $a$ and $n$ with $0 \leq a \leq m \leq n$ . If we set $a = 0$ and $n = m$ , then…
