✦ Synopsis

It is proved that for any Y E R n, n >_ 2, there is no Y-compatible polynomial function f : N n --~ Nk 1 < k < n. It is also proved that for a differentiable strict Y-compatible map f, Js(Y) = 0, where Jr(Y) denote the Jacobian matrix of the mapping f in Y. These problems arose in studying data compression of analog signatures.
