本文研究了给定阶数和大小的图中三角形个数的最小化问题,并描述了极图的渐近结构。这是通过描述使三角形密度最小化的标志代数同态的集合来实现的。
We consider the problem of minimizing the number of triangles in a graph of given order and size, and describe the asymptotic structure of extremal graphs. This is achieved by characterizing the set of flag algebra homomorphisms that minimize the triangle density.
