Abstract
Using a ribbon structure of the graph, we construct a dissection of the symmetric edge polytope of a graph into unimodular simplices. Our dissection is shellable, and one can interpret the elements of the resulting -vector via graph theory. This gives an elementary method for computing the -vector of the symmetric edge polytope.
