Abstract
Conditions are derived for the components of the normed limit of a multi-type branching process with varying environments, to be continuous on (0,∞). The main tool is an inequality for the concentration function of sums of independent random variables, due originally to Petrov. Using this, we show that if there is a discontinuity present, then a particular linear combination of the population types must converge to a non-random constant (Equation (1)). Ensuring this can not happen provides the desired continuity conditions.
