DESCRIPTION:Title: <a href="https://researchseminars.org/talk/MITNT/98/">H
 ilbert modular forms from definite orthogonal modular forms</a>\nby Eran A
 ssaf (Massachusetts Institute of Technology) as part of MIT number theory 
 seminar\n\nLecture held in Room 2-449 in the Simons Building (building 2).
 \n\nAbstract\nIn this talk\, we explicitly determine the relationship betw
 een Hilbert modular forms and positive-definite orthogonal modular forms\,
  with precise level structure and weight. This is achieved by analyzing th
 e interaction of the even Clifford functor with the p-neighbor relation on
  lattices. \nBy connecting our results to the theory of theta corresponden
 ce\, we present an application to the non-vanishing of theta maps.\nThis i
 s joint work with Dan Fretwell\, Colin Ingalls\, Adam Logan\, Spencer Seco
 rd and John Voight.\n
