On semistable Galois representations, by Kenneth A. Ribet

This paper has appeared in Pacific J. Math. 1997 Special Issue, 277-297 and so the dvi version has been removed. This article concerns two-dimensional semistable representations of the Galois group of Q over a finite etale F-algebra, where F is a finite field of characteristic different from 2 and 3. Generalizing work of Serre on semistable elliptic curves over Q, we show that the images of such representations are "as large as possible" whenever some mild necessary conditions are satisfied.
