Polyharmonic Green Functions and Nonlocal BMS Transformations of a Free Scalar Field

Carles Batlle, Victor Campello, Joaquim Gomis

We express the nonlocal BMS charges of a free massless Klein-Gordon scalar field in 2+1 in terms of the Green functions of the polyharmonic operators. Using the properties of these…
