%0 Journal Article %T Concerning Nikodym-type sets in 3-dimensional curved spaces %A Christopher D. Sogge %J Mathematics %D 1999 %I arXiv %X We obtain estimates for maximal functions that arise when one studies Nikodym-type sets. We also formulate a curvature condition that allows favorable estimates for these maximal functions. %U http://arxiv.org/abs/math/9912203v1
