Bas Edixhoven: Applying LLL to Hecke algebras.

Abstract:

It will be shown that the element T_p of the Hecke algebra of modular forms of weight k and level 1 can be computed in time polynomial in k and log p, if one accepts the Generalised Riemann Hypothesis. An application to counting points of given norm in lattices will be described.
