Unlike in the 1D case, the asymptotics contains a time independent term. The derivation of its spatial asymptotics is the technical core of the paper. Besides numerical applications, the obtained results play a crucial role in the analysis of spatio-temporal patterns for reaction-diffusion equations on lattices, in particular rattling patterns for hysteretic diffusion systems.<\/jats:p>","DOI":"10.3233\/asy-181498","type":"journal-article","created":{"date-parts":[[2019,3,8]],"date-time":"2019-03-08T10:37:48Z","timestamp":1552041468000},"page":"107-124","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":0,"title":["Asymptotics of the heat kernels on 2D lattices"],"prefix":"10.1177","volume":"112","author":[{"given":"Pavel","family":"Gurevich","sequence":"first","affiliation":[{"name":"Free University of Berlin, Germany.
