Abstract: | In this paper we characterise the graphs containing a (mathbb {Z} times mathbb {Z}) grid minor in a similar way as it has been done by Halin for graphs with an (mathbb {N} times mathbb {Z}) grid minor. Using our characterisation, we describe the structure of graphs without (mathbb {Z} times mathbb {Z}) grid minors in terms of tree-decompositions. |
