Consider partial maps Σ∗ −→ with a rational domain. We show that two families of such series are actually the same: the unambiguous rational series on the one hand, and ...
We prove in this paper that if r and s are two semilinear power series in commuting variables and s has bounded coefficients, then r-s is a rational series. This result can be tho...
We study the differential probability adp of exclusive-or when differences are expressed using addition modulo 2N . This function is important when analysing symmetric primitives t...
