Arithmetic Study Group: A Theta Lift in SL(2,1) and Locally Harmonic Maass Forms

Presented by Jonathan Crawford, Durham University

4 March 2014 13:00 in CM107

Modular forms of integral weight and half integral weight have many interesting applications in number theory. Shimura in 1973 defined a very important correspondence between the two which can be defined in the framework of theta lifts. More recently harmonic weak Maass forms (generalisations of classical modular forms) and their uses have been studied. In this talk I will discuss these objects and their properties and describe my work on a theta lift which links all of them together.
