Abstract

The conventional periodic boundary conditions in two dimensions permit generalizations upon the prescriptions by primitive vector-pairs not coinciding with the coordinate axes. Such extension furnishes the so-called toroidal boundary conditions which endow systems with more fruitful geometric structures. Equivalence relations can render the prescriptions geometrically more distinct, e.g., the full toroidal boundary conditions can be unambiguously specified simply by the twisting scheme. Moreover, physical significances can be collated based on more equivalent relations. Here, the general classification of finite-size scaling functions for the two-dimensional systems is in question. It is shown that a pattern of self-similarity emerges in the contours denoting distinctive finite-size scaling functions when depicted on the plane which parameterizes the toroidal geometry.
