1. Marc studied at the University of Leiden where he wrote a thesis on exponential polynomials.
2. For formal exponential polynomials over a field " K " we proceed as follows.
3. Eric Temple Bell called these the " exponential polynomials " and that term is also sometimes seen in the literature.
4. A more general framework where the term exponential polynomial may be found is that of exponential functions on abelian groups.
5. A product of additive functions and exponentials is called an exponential monomial, and a linear combination of these is then an exponential polynomial on " G ".
6. It's difficult to find exponential polynomials in a sentence. 用exponential polynomials造句挺難的
7. In mathematics, "'exponential polynomials "'are functions on rings, or abelian groups that take the form of polynomials in a variable and an exponential function.
8. An exponential variety over a field " K " is the set of points in " K " " n " where a finite collection of exponential polynomials simultaneously vanish.
9. Exponential polynomials on "'R "'and "'C "'often appear in transcendental number theory, where they appear as auxiliary functions in proofs involving the exponential function.
10. There is nothing particularly special about "'C "'here, exponential polynomials may also refer to such a polynomial on any exponential field or exponential ring with its exponential function taking the place of " e " " x " above.
11. The problem can be reduced to finding an effective procedure for determining whether any given exponential polynomial in " n " variables and with coefficients in "'Z "'has a solution in "'R " "'n " . showed that Schanuel's conjecture implies such a procedure exists, and hence gave a conditional solution to Tarski's problem.
12. If one defines an exponential variety to be the set of points in "'R " "'n " where some finite collection of exponential polynomials vanish, then results like Khovanski?'s theorem in differential geometry and Wilkie's theorem in model theory show that these varieties are well-behaved in the sense that the collection of such varieties is stable under the various set-theoretic operations as long as one allows the inclusion of the image under projections of higher-dimensional exponential varieties.
