Abstract: I will report on a work in progress about mirror symmetry for K3 surfaces in the spirit of the DHT conjecture. After giving a very brief introduction to the theory of pseudolattices, I will describe how they show up naturally in the context of Type II degenerations of K3 surfaces, and show how this can be used to recover some classical results due to Friedman. Time permitting, I will also discuss how these structures seem to provide a natural setting to study mirror symmetry for Type II degenerations of K3 surfaces. Everything is based on a joint work in progress with Alan Thompson.
