On the Graver complexity of codimension $2$ matrices

Abstract: In this paper we describe how the inherent geometric properties of the Graver bases of integer matrices of the form $\{(1,0),(1,a), (1,b),(1,a+b)\}$ with $a,b\in\z^+$ enable us to determine that the Graver complexity of the more general matrix $\A=\{(1, i_1),(1,i_2), (1,i_3),(1,i_4)\}$ associated to a monomial curve in $\p^3$ can be bounded as a linear relation of the entries of $\A$.

Keywords: Graver complexity, Hilbert bases, monomial curves

Classification (MSC2000): 14M25; 52B20, 13P99
