Seifert-fibre-edge conjecture. Every one-vertex triangulation of a small Seifert fibre space has an edge isotopic to a Seifert fibre.

Let $M=\left\{b;\left(\epsilon,g,(t,k)\right);\left(\ \mid \ \right); \left((p_1,q_1),\ldots,(p_r,q_r)\right)\right\}$ be a non-orientable closed irreducible and $\mathbb P^2$-irre…

Infinite Seifert-fibre counterexample conjecture. For every small Seifert fibre space that is not a lens space or prism manifold, there exist infinitely many one-vertex triangulati…
