%0 Journal Article %T Symmetric ladders and G-biliaison %A Elisa Gorla %J Mathematics %D 2008 %I arXiv %X We study the family of ideals generated by minors of mixed size contained in a ladder of a symmetric matrix from the point of view of liaison theory. We prove that they can be obtained from ideals of linear forms by ascending G-biliaison. In particular, they are glicci. %U http://arxiv.org/abs/0809.4337v2
