报告题目：The Iwasawa \mu-invariant of fine Selmer groups associated to general Drinfeld modules
报告摘要：Let F be any global function field over the finite field F_q where q is a prime power and A be the ring of elements in F regular outside \infty. Let \phi be an arbitrary Drinfeld module over F. For a fixed non-zero prime ideal P of A, we show that on the constant Z_p-extension \mathcal F of F, the Pontryagin dual of the fine Selmer group associated to the P-primary torsion of \phi over \mathcal F is a finitely generated Iwasawa module such that its Iwasawa \mu-invariant vanishes.
