Abstract: The Laplacian simplex of a finite simple graph is the convex hull of the columns of its Laplacian matrix. Since graphs can be seen as 1-dimensional simplicial complexes, we extend this approach to finite oriented simplicial complexes. Focusing on the boundary of \((d+1)\)-dimensional simplices, we will investigate serveral properties for the associated Laplacian polytopes as dimension, simpliciality, facet description and having a regular unimodular triangulation.
