Web1. By definition a graph is a set of edges E ⊆ V 2 and vertices. An other graph E ¯ ⊆ V ¯ 2 is equal if E = E ¯ and V = V ¯, but isomorphic if there exists a bijection f: V → V ¯ such that ( x, y) ∈ E ⇒ ( f ( x), f ( y)) ∈ E ¯. Isomorphic is as close as can be when the graphs not have identical sets of edges and vertices. Webisomorphisme , nom masculin. Sens 1. Chimie.

WebBy the construction of f we know that. ( x, y) = ( x ′ − y ′, x ′ + y ′). On the other hand, we can extract x ′ and y ′ through x and y from the last equation. We obtain. x ′ = x + y 2, y ′ = y − x 2. This formulas give a unique result for any x and y, hence we proved that f is isomorphic. WebSep 16, 2024 · Definition 9.7.2: Onto Transformation.
