Analytic Methods in Extremal Graph Theory

This talk discusses mainly two problems in extremal combinatorics where analytical methods can be used:
(1) What is the minimum number of F-subgraphs in a graph G with n vertices and a fraction of p edges? [supersaturated graphs]
(2) What is the minimum number of monochromatic copies of F in any red/blue-coloring of the complete n-vertex graph? [Ramsey multiplicity]
It is of some special interest if the minimum number is equal to the average number (attained by the random graph).

Most of this talk is based on work by A. F. Sidorenko.
