{{Short description|Type of surface singularity used in algebraic geometry}} {{one source |date=May 2024}} In algebraic geometry, an '''elliptic singularity''' of a surface, introduced by Philip Wagreich in 1970, is a surface singularity such that the arithmetic genus of its local ring is&nbsp;1.<ref>{{Citation |last=Wagreich |first=Philip |title=Elliptic singularities of surfaces |date=April 1970 |work=American Journal of Mathematics |volume=92 |issue=2 |pages=419-454 |publisher=The Johns Hopkins University Press |doi=10.2307/2373333 |issn=0002-9327 |jstor=2373333 |mr=0291170}}</ref>
