For instance: The sphereS2and a discboth have genus zero. A torushas genus one, as does the surface of a coffee mug with a handle. This is the source of the joke "topologists are people who can't tell their ... See more In mathematics, genus (plural genera) has a few different, but closely related, meanings. Intuitively, the genus is the number of "holes" of a surface. A sphere has genus 0, while a torus has genus 1. See more Orientable surfaces The genus of a connected, orientable surface is an integer representing the maximum number of cuttings along non-intersecting See more Genus can be also calculated for the graph spanned by the net of chemical interactions in nucleic acids or proteins. In particular, one may … See more There are two related definitions of genus of any projective algebraic scheme X: the arithmetic genus and the geometric genus.

Minimal genus for 4-manifolds with b + = 1. J Topol, 2016, 9 (1): 5–26 Article MathSciNet MATH Google Scholar WebFor computing the genus, we need an algorithm for solving the following decisive problem: for a real plane algebraic curve C defined by the polynomial f (x,y)=0, we need to compute a graph G= (V,E), where V is a set of points in the 2-dimensional Euclidean plane together with their Euclidean coordinates and E is a set of edges connecting them.
