Formation of Iridium(III) Complexes via Selective Activation of the C–H and N–H Bonds of a Dipyridylpyrrole Ligand

, 2020
Treatment of [Ir­(PPh3)3Cl] with 2-[5-(pyridin-2-yl)-1H-pyrrol-2-yl]­pyridine (Hdpp) in refluxing toluene affords an unexpected pyrrole-metalated iridium­(III) hydride complex, [Ir­(K2C,N-dpp)­(H)­(Cl)­(PPh3)2] (1), via Cpyrrole–H activation, while the ...

Suppressors of order 6, 8 and 10 for any fitness value.

, 2018
In [7], we called ℓ-graph the undirected graph of even order N = 2n + 2 ≥ 6 obtained from the clique K2n by dividing its vertex set into two halves with n ≥ 2 vertices and adding 2 extra vertices. Each of them is connected to one of the halves of K2n and

The study of the star arboricity of complete bipartite graphs

, 2010
碩士假設V1﹐V2為兩個集合﹐若V＝V1∪V2﹐V1∩V2＝Φ且E＝{uv︱u V1, v V2}﹐則稱(V, E)為完全二分圖。若︱V1︱＝m﹐︱V2︱＝n﹐則此完全二分圖記為Km,n。當︱V1︱＝1﹐︱V2︱＝n﹐稱K1,n為星圖﹙Star﹚。當圖G的每一個最大連通子圖都是星圖時﹐我們稱圖G為星林圖﹙Star-forest﹚。將圖G分割成邊相異之星林圖時﹐其最少星林圖的個數稱為G的星林分解數﹐用*(G)表示。 在本論文中﹐我們考慮的是完全二分圖K2n,2n+4﹐n≧3的星林分解數 ...

On k-Nearest Neighbor Voronoi Diagrams in the Plane

, 2014
The notion of Voronoi diagram for a set of N points in the Euclidean plane is generalized to the Voronoi diagram of order k and an iterative algorithm to construct the generalized diagram in 0(k2N log N) time using 0(k2(N − k)) space is presented.
