Center node: "on the complexity of finding large odd induced subgraphs and odd colorings"
  Abstract: We study the complexity of the problems of finding, given a graph $G$, a largest induced subgraph of $G$ with all degrees odd (called an odd subgraph), and the smallest number of odd subgraphs that partition $V(G)$. We call these parameters ${\sf mos}(G)$ and $\chi_{\sf odd}(G)$, respectively. We prove that deciding whether $\chi_{\sf odd}(G) \leq q$ is polynomial-time solvable if $q \leq 2$, and NP-complete otherwise. We provide algorithms in time $2^{O({\sf rw})} \cdot n^{O(1)}$ and $2^{O(q \cdot {\sf rw})} \cdot n^{O(1)}$ to compute ${\sf mos}(G)$ and to decide whether $\chi_{\sf odd}(G) \leq q$ on $n$-vertex graphs of rank-width at most ${\sf rw}$, respectively, and we prove that the dependency on rank-width is asymptotically optimal under the ETH. Finally, we give some tight bounds for these parameters on restricted graph classes or in relation to other parameters.
