The University of Arizona for their generous financial support. I would also like to acknowledge María Gutiérrez for generous assistance in fieldwork and Carol Placchi for her assistance in producing the graphics in this paper. Special thanks are due to Diana Hadley and Larry Marshall for all the important doors they opened that allowed this research to be so fruitful and to Phil Halpenny for h...

Liaison Linkages

The complete classification of hexapods — also known as Stewart Gough platforms — of mobility one is still open. To tackle this problem, we can associate to each hexapod of mobility one an algebraic curve, called the configuration curve. In this paper we establish an upper bound for the degree of this curve, assuming the hexapod is general enough. Moreover, we provide a construction of hexapods...

Liaison Addition and the Structure of a Gorenstein Liaison Class

We study the concept of liaison addition for codimension two subschemes of an arithmetically Gorenstein projective scheme. We show how it relates to liaison and biliaison classes of subschemes and use it to investigate the structure of Gorenstein liaison equivalence classes, extending the known theory for complete intersection liaison of codimension two subschemes. In particular, we show that o...
