Abstract

In the present paper, we determine the algebraic relations among the tractable coordinates of logarithms of Anderson tt-modules constructed by taking the tensor product of Drinfeld modules of rank rr defined over the algebraic closure of the rational function field and their (r1)(r-1)-st exterior powers with the Carlitz tensor powers. Our results, in the case of the tensor powers of the Carlitz module, generalize the work of Chang and Yu on the algebraic independence of polylogarithms.
