[2,3]-factors in a 3-connected infinite planar graph

For two integersm, n withm<-n, anm, n]-factorF in a graphG is a spanning subgraph ofG withm<-d _F (v)<-n for allv∈V(F). In 1996, H. Enomoto et al. proved that every 3-connected planar graphG withd _G (v)>-4 for allv∈V(G) contains a 2,3]-factor. In this paper we extend their result to all 3-connected locally finite infinite planar graphs containing no unbounded faces.
