this talk, we will discuss the dichotomy recurrence/transience and ballisticity
in the context of a class of random walks that build their own domain. At each
step of the walker on its domain, a random number of new vertices is attached
to the walker's position. We will present distributional conditions over this
random number of new vertices for which we observe distinct sharp behavior on
the walker. We also discuss structural results, that is, when this process is
seen as a random graph model, the walker is capable of generating trees whose
degree distribution approaches a power-law.</span><span lang="EN-US" style="font-size:12pt;line-height:115%;background-image:initial;background-position:initial;background-size:initial;background-repeat:initial;background-origin:initial;background-clip:initial"></span></p>
