Recently Bezerra, Garcia and Stichtenoth constructed an explicit tower F = (F n ) n 0 of function fields over a finite field F q 3 , whose limit ฮป(F ) = lim nโโ N(F n )/g(F n ) attains the Zink bound ฮป(F ) 2(q 2 -1)/(q + 2). Their proof is rather long and very technical. In this paper we replace the
