| Abstract | In 1906, Fatou proved two rational-transcendental dichotomy theorems on power series: (1) a power series with finitely distinct coefficients is either rational or transcendental; (2) a power series with integer coefficients and of radius of convergence 1 is either rational or transcendental. Fatou's theorems were later extended in the work of other mathematicians, such as Polya, Carlson, and Szego. The classical results are mainly focusing on the univariate power series. In this talk, we will present some multivariate extensions of Fatou's theorems for D-finite power series. |
