摘要：

We calculate the formal group law that represents the completion of the Neron model for an algebraic torus over Q split in a tamely ramified abelian extension. To that end, we introduce an analogue of the fixed part of a formal group law with respect to a group action and give a method to compute its Honda p-types.
