DESCRIPTION:We introduce a geodesic slice sampler on the Euclidean sphere
(in arbitrary but fixed dimension) that can be used for approximate sampli
ng from distributions that have a density with respect to the correspondin
g surface measure. Such distributions occur e.g. in the modelling of direc
tional data or shapes. Under some mild conditions we show that the corresp
onding transition kernel is well-defined\, in particular\, that it is reve
rsible with respect to the distribution of interest.\nMoreover\, if the de
nsity is bounded away from zero and infinity\, then we obtain a uniform er
godicity convergence result.\n\nhttps://conference2.aau.at/event/131/contr
