About: Barth surface

An Entity of Type: Surface104362025, from Named Graph: http://dbpedia.org, within Data Space: dbpedia.org

In algebraic geometry, a Barth surface is one of the complex nodal surfaces in 3 dimensions with large numbers of double points found by Wolf Barth. Two examples are the Barth sextic of degree 6 with 65 double points, and the Barth decic of degree 10 with 345 double points. For degree 6 surfaces in P3, David Jaffe and Daniel Ruberman showed that 65 is the maximum number of double points possible.The Barth sextic is a counterexample to an incorrect claim by Francesco Severi in 1946 that 52 is the maximum number of double points possible.
