Graph families | Perfect graphs
In the mathematical area of graph theory, a k-leaf power of a tree T is a graph G whose vertices are the leaves of T and whose edges connect pairs of leaves whose distance in T is at most k. That is, G is an induced subgraph of the graph power , induced by the leaves of T. For a graph G constructed in this way, T is called a k-leaf root of G. A graph is a leaf power if it is a k-leaf power for some k. These graphs have applications in phylogeny, the problem of reconstructing evolutionary trees. (Wikipedia).
Energy, Work & Power (24 of 31) Power, An Explanation
Gives an explanation of what power is in physics. Includes a explanation of horsepower and one worked example. Power is the rate a which work is done. Also stated as how fast work is done. Power is calculated as the amount of work done divided by the time it takes to do the specified amo

We consider an algebraic $V$ variety and its foliation, both defined over a number field. Given a (compact piece of a) leaf $L$ of the foliation, and a subvariety $W$ of complementary codimension, we give an upper bound for the number of intersections between $L$ and $W$. The bound depends
