An intrinsically linked simplicial $n$-complex

Abstract

For any positive integer nn, Lov\'{a}sz-Schrijver, Taniyama and Skopenkov provided examples of simplicial nn-complexes that inevitably contain a nonsplittable two-component link of nn-spheres, no matter how they are embedded into the Euclidean (2n+1)(2n+1)-space. In this paper, we introduce a new example of such a simplicial nn-complex through a simple argument in piecewise linear topology and an application of the van Kampen--Flores theorem. Furthermore, we demonstrate the existence of additional such complexes through higher dimensional generalizations of the Y\triangle Y-exchange on graphs.
