The mapping ~= 1+x~2_ 1is studied. The x,, i= 1, 2, 3, are independent random variables with common distribution. This mapping describes growth under fluctuating conditions, as may occur,e.g., in biology and economics. It also shows up in the grand canonical description of a directed polymer, bound to a wall of a random (1 + 1)-dimensional medium, in the… CONTINUE READING
