Let G be a graph and let V(G) be the vertex set of G. Define the neighborhood complex N(G) as the simplicial complex whose simplices are those subsets of V(G) which have a common neighbor.
一个图G的邻域复形是以G的顶点为顶点,以G的具有公共邻接顶点的顶点子集为单形的抽象复形。
V : Here, step over to the chalkboard and let me show you a simple problem.
过来, 走到黑板前,让我给你示范一个简单的问题。
When you're finished with that, let us now transfer that to our canvas using the Move tool (v).
当您与该完成的,现在让我们转移,为我们的画布上使用移动工具(五)。
So the first path then, the first path, 1 constant volume constant V, so I'm going to, again, let's just worry about energy.
首先,是路径,等压过程。
v We don't know what it is yet. In order to change this from a p to a V, you have to use the chain rule. So let's use the chain rule.
为了把这里的p变成,我们需要利用链式法则,好,让我们使用链式法则。
So I just have to see, oh, here's a D, let me keep looking, D here's an A, keep looking here's a V, here's an I, here's a D and yet, and this is one tidbit we introduced a week or so ago, how do I now know if I'm just given the address of the start of the string where the end is?
我只需要看到,哦,这里是一个D,让我接着往下看,这里是A,接着这是V,这是I,这是,然而,这是我们一周以前介绍的花絮,如果你给我一个字符串开始的地址,我怎么知道它什么时候结束?
