Abstract

In this paper, we discuss generating theorems of polyhedral quadrangulations of closed surfaces. We prove that the set of the eight reductional operations {R1, …, R8} defined for polyhedral quadrangulations is finitizable for any closed surface F2, that is, there exist finitely many minimal polyhedral quadrangulations of F2 using such operations R1, …, R7 and R8. Furthermore, we show that any proper subset of {R1, …, R8} is not finitizable for polyhedral quadrangulations of the torus.
