One of the main problems of the theory of dynamical systems is the determination of the existence of periodic orbits of a self-map and more generally, the structure of the set of periods. Define the m...
Spanning Trees on Hypercubic Lattices and Non-orientable Surfaces
Trees Hypercubic Lattices Non-orientable Surfaces
