* The Gentry-Szydlo algorithm to perform a halving of dimension by working in the totally real subfield of the cyclotomic field.

* A q-descent procedure using lattice reduction and ideal arithmetic to reduce the problem to PIP for L(1/2)-smooth ideals.

* A linear algebra phase to solve the L(1/2)-smooth instances.

All along the presentation we will emphasize on the relations between the commutative algebra side (ideals arithmetic, manipulations of number field elements,...) and the geometric side (norms related issues, lattice reduction,...).
