随机几何图中的Hamilton圈

Hamilton cycles in random geometric graphs

József Balogh, Béla Bollobás, Michael Krivelevich, Tobias Müller, Mark Walters

摘要:

我们证明了,在吉尔伯特模型的随机几何图,几乎每一个图成为哈密尔顿正是当它第一次成为2-连通。这回答了彭罗斯的一个问题。我们还证明了在k-近邻模型中,存在一个常数κ使得几乎每个κ-连通图都有一个Hamilton圈.

英文摘要:

We prove that, in the Gilbert model for a random geometric graph, almost every graph becomes Hamiltonian exactly when it first becomes 2-connected. This answers a question of Penrose. We also show that in the k-nearest neighbor model, there is a constant κ such that almost every κ-connected graph has a Hamilton cycle.
