Jet Spaces of Varieties over Diierential and Diierence Elds
نویسندگان
چکیده
We give elementary proofs, using suitable jet spaces, of some old and new structural results concerning nite-dimensional diierential algebraic varieties (characteristic zero). We prove analogous results for diierence algebraic varieties in characteristic zero. We also mention partial results and problems in the positive characteristic case.

متن کاملExponential Stability in Mean Square of Neutral Stochastic Differential Difference Equations
In this paper we shall discuss the exponential stability in mean square for a neutral stochastic diierential diierence equation of the form dx(t) ? G(x(t ?))] = f(t; x(t); x(t ?))dt + (t; x(t); x(t ?))dw(t). In the case when (t; x; y) 0 this neutral stochastic diierential diierence equations becomes a deterministic neutral diierential diierence equations d dt x(t)?G(x(t?))] = f(t; x(t); x(t?))....
متن کاملFlaws in Diierential Cryptanalysis of Skipjack
This paper is motivated by some results presented by Knud-sen, Robshaw and Wagner at Crypto'99 3], that described many attacks of reduced versions of Skipjack, some of them being erroneous. Diierential cryptanalysis is based on distinguishers, any attack should prove that the events that triggers the analysis has not the same probability for the cipher than for a random function. In particular,...
