Abstract: | We consider a branching random walk with values in a certain set , where the branching mechanism is different according to whether particles (individuals) are in a certain so called trapping set or not. We are then interested, under different scenarios, in properties of either the transient random measure describing distribution of individuals on over time or its asymptotic behaviour. |
