The main goal this thesis is to study the relations among some special zeta values. It contains 6 chapters.The first chapter is devoted to present some basic definitions and properties of Drinfeld modules, the Carlitz modules, its related objects (such as the Carlitz exponential map and the Carlitz period) and Tate algebras in several variables. The second chapter is to present a special several variable polynomial which is closely related to the zeta values in Tate algebras.In Chapter 3, we study the zeta values in Tate algebras which is introduced by Pellarin in 2012. We give an affirmative answer to a conjecture of Pellarin about identities for these zeta values. We also suggest a conjecture about the coefficients of the special several ...
