| Abstract: We explain a relation between the crystalline cohomology of the Igusa tower and the Iwasawa module of ordinary Lambda-adic cusp forms. By studying the de Rham cohomology of Igusa curves in characteristc p, we will use this relation to give a new proof of the existence of ordinary families of cuspforms. |
