Lattice invariants and teralattice pairs
Abstract:
I want to recall the theta series of a lattice. This is a nice invariant
which gives a modular form for each integral lattice. However, there are
lattice pairs which share the same theta series. We recall a construction
of such pairs.
Together with J. Cervino we developed new lattice invariants which
generalize the theta series. I will show how these invariants distinguish
the lattice pairs in the above family.
