โฆ Synopsis
For a commutative differential algebra., , if (p_{1}) and (p_{2}) are prime ideals with (p_{1} \subset p_{2}, p_{1} \neq p_{2}), and (D\left(p_{1}\right)) not contained in (p_{2}), then there exists a prime ideal (p_{3} \subset p_{2}), with (p_{3} \not p_{1}) and (p_{1} \not p_{3}) and (\left{x \mid D^{k} x \in p_{1}\right.) for all (\left.k \geqslant 0\right} \subset p_{3}). This yields an alternative proof that there is no non-trivial derivation on (C^{k}([0,1])) and gives a generalized existence theorem for polarized prime ideals of (C^{2}([0,1], C)).

Let R be a commutative algebra over a field k. We prove two related results on the simplicity of Lie algebras acting as derivations of R. If D is both a Lie subalgebra and R-submodule of Der k R such that R is D-simple and either char k = 2 or D is not cyclic as an R-module or D R = R, then we show
The theory of stochastic processes has been traditionally developed in terms of random variables and their joint distributions. This is not surprising since the definition of a stochastic process is abstracted from numerical statistical data that are empirically observed and to which the notion of a
We determine the commutant algebra of W in the m-fold tensor product of its n natural representation in the case m F n. For m ) n, we show that the commutant algebra is of finite dimension by introducing a new kind of harmonic polynomial.
