WebThe genus of a connected surface (i.e. a connected topological space any point of which has a neighborhood homeomorphic to the plane) is the maximum number of simple closed curves without common points that … Webdegree-genus formula is far from trivial, and requires a modest background in the properties of complex algebraic curves, as well as some results from topology. This paper will be written assuming the reader has an adequate background. 2. One Method of Proof Recall that a complex algebraic curve is the set of zeroes of a homogeneous
WebIn this context another genus, the arithmetic genus, played an important role. In the early 1950s four definitions of the arithmetic genus of a projective smooth algebraic variety V of com-plex dimension n were known. The first two are denoted by pa(V) and Pa(V). Severi conjectured that these numbers agree and can be computed in WebIs there a computationally efficient way to determine the genus (i.e. number of handles) of the surface represented by the mesh? ... algebraic-topology; algorithms; graph-theory; Share.
