Hrrmm.. well, for instance, in the case of factoring; there are efficient approaches to polynomial reduction using PDE methods. Although I was perhaps (somewhat incorrectly) thinking that capturing the effects of a apparantly random process using stochastic differential equations might have been relevant. With regards to complex analysis, it is important to number theory. For instance, the use of Riemann Zeta function within prime number theory. The riemann zeta function is a function of a complex variable. Also applicable to sieve theory. oh well.. I'm off to bed. - john
