During Prof. Yevgeniy Kovchegov's visit to the University of São Paulo, we will work on extending our method that utilizes the hydrodynamic limits of coalescent processes for finding the mean length of the minimal spanning trees in random graphs. Also, we will examine the gelation phenomenon in the Marcus-Lushnikov dynamics with multidimensional weight vectors. We will test the usability of the coalescent processes with multidimensional weight vectors as models of genetic drift viewed backwards in time. Finally, we will continue our joint work that examines so called 'unexpected correlations' in biological networks using the methods of statistical mechanics, thus extending our previous results.
