Modified Low conjecture. Two events are causally unrelated if and only if the lifts of their fronts are unlinked in the appropriate sense.

Consider the two nodal manifolds associated with the minimal multifold-node models inside an enclosing sphere $S^\ell$. Suppose that their nontrivial cycles occur in complementary…

For almost embeddings of graphs in the plane, the paper studies integer-valued linking invariants, including the invariant $w_f(C,v)$ associated with an oriented cycle $C$ and a ve…

The paper considers almost embeddings of graphs in the plane and the integer invariants associated with them, as well as their algebraic analogues, namely $\mathbb Z$-embeddings an…

Loop linking number conjecture. The loop linking number of $d4d0$ associated to every tensor $\Lambda\in\operatorname{TLG}(d4d0,G)$ is trivial.

Non-classification conjecture. The analogue of the doodle-concordance correspondence for $k=1$ is false for every $r\geq 4$.
