Abstract
In this article we give a new proof for the infinitesimal Torelli theorem for minimal elliptic surfaces without multiple fibers with Euler number at least 24 for nonconstant -invariant. In the case of constant -invariant we find a new proof in the case of Euler number at least 72. We also discuss several new counterexamples.
