Abstract:
We suggest a method for selecting an LL-simplex in an LL-polyhedron of an nn-lattice in Euclidean space. By taking into account the specific form of the condition that a simplex in the lattice is an LL-simplex and by considering a simplex selected from an LL-polyhedron, we present a new method for describing all types of LL-polyhedra in lattices of given dimension nn. We apply the method to deduce all types of LL-polyhedra in nn-dimensional lattices for n=2,3,4n=2,3,4, which are already known from previous results.
