In 2012, Taelman proved a class formula for -series associated to Drinfeld -modules and considered it as a function field analogue of the Birch and Swinnerton-Dyer conjecture. Since then, Taelman's class formula has been generalized to the setting of Anderson -modules. Let be a monic irreducible polynomial of , we define the -adic -series associated with Anderson -modules and prove a -adic class formula à la Taelman linking a -adic regulator, the class module and a local factor at . Next, we study the vanishing of the -adic -series and give some applications to Drinfeld modules defined over itself. Finally, we extend this result to the multi-variable setting à la Pellarin.
