Hankel Matrices: From Words to Graphs
... Weighted RMSOL vs. MSOLEVAL, II In contrast to these disadvantages, MSOLEVALF has the following advantages: (i) The expressions are natural and intuitive. (ii) The expressions are defined for all formulas of MSOL without any restrictions. (iii) If we replace formulas occurring in an expression by eq ...

Large Graphs and Graph Limits
... We consider sequences of large graphs which have certain convergent graph parameters. Many important graph parameters like the edge density may be represented asymptotically as homomorphism densities. I turns out that convergence of homomorphism densities of a graph sequence gives rise to distance b ...
