    Ordinary p-adic étale Cohomology Groups Attached to Towers of Elliptic Modular Curves

    Fix a prime number p ≥ 5 and a positive integer N prime to p. We consider the projective limits of p-adic étale cohomology groups of the modular curves X1(Npr) and Y1(Npr) (r ≥ 1), which are denoted by ESp(N) Z p
