Three types of Hermite-Pade approximants are considered, known respectively as quadratic, integral and differential Pade approximants. The singularity structure of each type of approximant is described. It is more complicated than that of the standard Pade approximant, and this property may often be used to estimate the types of singularity of a function from its power series expansion, as well as evaluate it on its branch cuts. Two applications in different fields are described which… CONTINUE READING
