Algebraic values of certain analytic functions defined by a canonical product.
The Bombieri-Pila theorem predicts a bound of the form c(f,ϵ)Hϵ for the number of rational points of height at most H on the graph of a (real analytic) transcendental function f restricted to a compact interval. Although this bound is sharp in general, for certain special cases (such as those arising under additional hypotheses on f) it can be improved to a poly-logarithmic bound in H. In our recent work we obtain a C(logH)η bound for the number of algebraic points of bounded degree and height at most H on certain subsets of graphs of a family of entire functions defined by a canonical product.
