We discuss a phenomenon of critical fluctuations, demonstrating that an epidemic can behave very differently even if it runs on the same network, with the same transmission probabilities and started from the same initial seeds. We explore a connection between the geographic distribution and intensity of the spreading epidemic. We argue that the speed of the spread of an epidemic depends not only on the number of current infections, but also on their geographic distribution over a country. Through the observations of these phenomena we suggest a dependence of the final epidemic size on the geometric position of initial seeds of an epidemic process.}, keywords = {PERCOLATION; Epidemic models; geometricnetworks; epidemic seeding; switchover phenomenon}, year = {2022}, eissn = {2732-2688}, pages = {409-417}, orcid-numbers = {Lovász, László/0000-0001-6596-0465; Karsai, Márton/0000-0001-5382-8950} } @{MTMT:30358959, title = {Modified box dimension of trees and hierarchical scale-free graphs}, url = {https://m2.mtmt.hu/api/publication/30358959}, author = {Komjáthy, Júlia and Molontay, Roland and Simon, Károly}, booktitle = {Complex Networks 2018: The 7th International Conference on Complex Networks and Their Applications}, unique-id = {30358959}, year = {2018}, pages = {290-293} } @inproceedings{MTMT:3123334, title = {Topics in Markov chains: Mixing and escape rate}, url = {https://m2.mtmt.hu/api/publication/3123334}, author = {Komjáthy, Júlia and Peres, Y}, booktitle = {PROBABILITY AND STATISTICAL PHYSICS IN ST.

We also claimed two models with concave hydrodynamic flux which satisfied the assumptions which made our proof work. In the present note we show that the totally asymmetric exponential bricklayers process also satisfies these assumptions. Hence this is the first example with convex hydrodynamics of a model with t^{1/3}-order current fluctuations across the characteristics. As such, it further supports the idea of universality regarding this scaling.}, year = {2012}, eissn = {1572-9613}, pages = {35-62} } @article{MTMT:2215759, title = {Microscopic concavity and fluctuation bounds in a class of deposition processes}, url = {https://m2.mtmt.hu/api/publication/2215759}, author = {Balázs, Márton and Komjáthy, Júlia and Timo, Seppäläinen}, doi = {10.1214/11-AIHP415}, journal-iso = {ANN I H POINCARE-PR}, journal = {ANNALES DE L INSTITUT HENRI POINCARE-PROBABILITES ET STATISTIQUES}, volume = {48}, unique-id = {2215759}, issn = {0246-0203}, year = {2012}, eissn = {1778-7017}, pages = {151-187} }
