Title: An introduction to weighted polynomial approximation in the complex domain – part 2
Abstract: This is the second part of the talk, but it should be mostly independent of the first part. We shall discuss the conditions under which a measure on a union of rays is uniquely determined by its Fourier transform. The result (based on joint work with Gady Kozma) is a generalisation of a theorem of Vul from 1959. The proof is based on a new Phragmén-Lindelöf principle, which may be of independent interest.
