In this paper, we research the Miintz rational approximation of two kinds of spe- cial function classes, and give the corresponding estimates of approximation rates of these classes.
Many results on the arithmetic theory of elliptic curves have been obtained for elliptic curves with complex multiplication by Z[i], e.g. [1]—[3], which can be considered as the simplest case. The next simplest case ...Many results on the arithmetic theory of elliptic curves have been obtained for elliptic curves with complex multiplication by Z[i], e.g. [1]—[3], which can be considered as the simplest case.
