Embeddings of $k$ -complexes in $2 k$ -manifolds and minimum rank of partial symmetric matrices

A. Skopenkov

Let $K$ be a $k$ -dimensional simplicial complex having $n$ faces of dimension $k$ , and $M$ a closed $(k - 1)$ -connected PL $2 k$ -dimensional manifold. We prove that for $k \geq 3$ odd $K…

Invariants of almost embeddings of graphs in the plane

E. Alkin, A. Miroshnikov, A. Skopenkov

A graph drawing in the plane is called an almost embedding if the images of any two non-adjacent simplices (i.e. vertices or edges) are disjoint. Almost embeddings (more precisely,…
