Resumen:
We investigate finite size scaling aspects of disorder reaction-diffusionprocesses in one dimension utilizing both numerical and analytical approaches. The former averages the spectrum gap of the associatedevolution operators by doubling their degrees of freedom, while thelatter uses various techniques to map the equations of motion to a first passage time process. Both approaches are consistent with nonuniversal dynamic exponents, and with stretched exponential scaling forms for particular disorder realizations.
