http://math.fau.edu/locke/Center.htm WebDefinition A.1.14 (Planar graph) A graph G = (N,E) is planar if it can be drawn in the plane in such a way that no two edges in E intersect. Note that a graph G can be drawn in several different ways; a graph is planar if there exists at least one way of drawing it in the plane in such a way that no two edges cross each other (see Figure A.2).

WebMar 24, 2024 · Let A be an n×n matrix with complex or real elements with eigenvalues lambda_1, ..., lambda_n. Then the spectral radius rho(A) of A is rho(A)=max_(1<=i<=n) lambda_i , i.e., the largest absolute value (or complex modulus) of its eigenvalues. The spectral radius of a finite graph is defined as the largest absolute value …
WebMar 28, 2015 · Using Let d (x, z) = diameter (G) and let y be a center of G (i.e. there exists a vertex v in G such that d (y, v) = radius (G)). Because d (y, v) = radius (G) and d (y, v) = d (v, y), we know that d (v, z) <= radius (G). Then we have that diameter (G) = d (x, z) <= d (y, v) + d (v, z) <= 2*radius (G).
