WebThe maximum genus γM (G) of a connected graph G has been defined in [2] as the maximum g for which there exists an embedding h : G —> S (g), where S (g) is a compact orientable 2-manifold of genus g,…. Expand. 14. View 3 excerpts, cites methods and … The genus of a connected, orientable surface is an integer representing the maximum number of cuttings along non-intersecting closed simple curves without rendering the resultant manifold disconnected. It is equal to the number of handles on it. Alternatively, it can be defined in terms of the Euler characteristic χ, via the relationship χ = 2 − 2g for closed surfaces, where g is the genus. For surfaces with b boundary components, the equation reads χ = 2 − 2g − b. In layman's terms, … tshirt sublimation pattern
