ON THE LOGARITHIMIC CALCULUS AND SIDORENKO's CONJECTURE

Janet Li

Joint work with Balazs Szegedy.
We study a type of calculus for proving inequalities between 
subgraph densities which is based on Jensen's inequality for 
the logarithmic function. As a demonstration of the method we verify 
the conjecture of Erd¨os-Simonovits and Sidorenko for new families
of graphs. In particular we give a short analytic proof for a 
result by Conlon, Fox and Sudakov.
