%0 Journal Article %T The Minkowskian planar 4R mechanism %A Gabor Heged¨šs %A Brian Moore %J Mathematics %D 2010 %I arXiv %X We characterize and classify completely the planar 4R closed chain working on the Minkowskian plane. Our work would open a new research direction in the theory of geometric designs: the classification and characterization of the geometric design of linkages working in non--Euclidean spaces. %U http://arxiv.org/abs/1010.5668v1
