A Polynomial Time Algorithm for Steiner Tree When Terminals Avoid a Rooted K₄-Minor
We study a special case of the Steiner Tree problem in which the input graph does not have
a minor model of a complete graph on 4 vertices for which all branch sets contain a terminal …

Toward Gr\" unbaum's Conjecture
C Ortlieb, JM Schmidt - arXiv preprint arXiv:2402.05681, 2024 - arxiv.org
Given a spanning tree $ T $ of a planar graph $ G $, the co-tree of $ T $ is the spanning tree
of the dual graph $ G^* $ with edge set $(E (G)-E (T))^* $. Gr\" unbaum conjectured in 1970 …
